(2016) Journal of Nursing Management Work–family conflict and enrichment in nurses: between job demands, perceived organisational support and work–family backlash Aim This study investigated how work relationships (perceived organisational support, supervisor and co-worker work–family backlash) and job demands (workload, emotional dissonance) can interact with work–family conflict and work–family enrichment. Background Despite the extensive literature on the work–family interface, few studies on the nursing profession have considered the role of job demands and work relationships, focusing on both the positive and negative side of the work– family interface. Method The study involved a sample of 500 nurses working in an Italian hospital. Hierarchical multiple regression analyses were used to test hypotheses. Results Analyses showed that work–family conflict has a positive relationship with job demands and supervisor backlash, and a negative relationship with perceived organisational support. Work–family enrichment was found to have a negative relationship with job demands and a positive relationship with perceived organisational support. No significant relationships were found between work– family enrichment and both backlash dimensions. Conclusion The study confirmed the importance of promoting a balance between job demands and resources in order to create favourable conditions for work– family enrichment and to prevent work–family conflict. Implications for nursing management The findings suggest that it may be advisable for health-care organisations to invest in measures at individual, team and organisational levels, specifically in training and counselling for nurses and supervisors. Keywords: job demands, nurses, perceived organisational support, work–family backlash, work–family conflict, work–family enrichment Accepted for publication: 20 September 2016 DOI: 10.1111/jonm.12442 ª 2016 John Wiley & Sons Ltd 1 C. Ghislieri et al. Introduction The number of studies on the work–family interface has increased over the past decades, following changes in demographics (more dual-earner or dual-career couples and single-parent families) and working conditions (more job insecurity and more blurring of boundaries between work and life; Ghislieri & Colombo 2014). As a result of these changes, workers are less able to handle tasks and demands from both work and family domains effectively. The issues of work–family conflict (WFC) and work–family enrichment (WFE) are central to understanding work dynamics in organisations and the relation among work and other life fields. This is especially true for the nursing profession (Cortese et al. 2010, Ghislieri et al. 2011), where scholars have suggested that WFC is related to lower work satisfaction and higher turnover intentions, as well as burnout and health impairment (Grzywacz et al. 2006, van der Heijden et al. 2008, Cortese et al. 2010), while WFE is related to higher levels of professional commitment and lower intentions to leave the profession (Russo & Buonocore 2012, Tummers & Den Dulk 2013, Ghislieri et al. 2015). The study used a sample of Italian nurses to explore how certain job demands and specific kinds of work relationships can interact with WFC and WFE. A number of studies highlighted how job demands, specifically workload and emotional dissonance (Bakker & Heuven 2006), were among the main determinants of WFC in the various contexts where the relationship with others was central (Cortese et al. 2010, Ghislieri et al. 2012). The relation between job demands and WFE has been less investigated in the literature since enrichment is mainly linked to resources, even though recent studies have shown the relevance of a certain level of job demands in fostering work engagement and activation on the job (Bakker et al. 2010). Concerning work relationships, this study focused on two aspects that have rarely been investigated, to date. Only a few investigations have considered general perceived organisational support (POS), emphasising the ‘antidote effect’ of the negative consequences of WFC (Casper et al. 2002) and hypothesising that organisational support provides a feeling that socioemotional needs are fulfilled, which in turn ‘allows people to derive benefits from work and apply them to family life (i.e. WFE)’ (McNall et al. 2011, p. 137). McNall et al. (2011) confirmed the strong positive relationship between POS and WFE. 2 Another topic considered in the literature but less investigated in empirical research is work–family backlash (Young 1999), defined as the resentment that workers feel from supervisors and co-workers towards their efforts to balance work and family life (Korabik & Warner 2009, Colombo & Ghislieri 2014). Few studies have investigated backlash and its relation to work–family balance perceptions (Ricotta et al. 2011). To summarise, the objective of this study was to investigate the relationships between two job demands (workload and emotional dissonance) and three work relationships (POS, supervisor backlash and co-worker backlash) as antecedents, and WFC and WFE as outcome variables. Theoretical background WFC and enrichment in nurses The work–family interface is defined as the process in which an individual’s functioning in the work (or family) domain is influenced by pressures and resources from the family (or work) domain (Bakker et al. 2011). Among the theoretical models, which address the work–family interface, the conflict perspective dominated for most of the 1980s and 1990s, while the enrichment perspective has become increasingly important in the past two decades (Ghislieri et al. 2011, Russo & Buonocore 2012). The WFC model originates from role theory (Merton 1957) and from Goode’s (1960) role strain hypothesis. Work–family conflict has been defined as ‘a form of inter-role conflict in which the role pressures from the work and family domains are mutually incompatible in some respect. That is, participation in the work (family) role is made more difficult by virtue of participation in the family (work) role’ (Greenhaus & Beutell 1985, p. 77). Work–family conflict may be due to time issues, but may also derive from different kinds of stressors or from incompatible behavioural demands. Recently, scholars have focused their attention on the link between WFC and WFE. Enrichment is a process whereby one role enhances the quality of the other: ‘work-to-family enrichment occurs when work experiences improve the quality of family life, and family-to-work enrichment (FWE) occurs when family experiences improve the quality of work life’ (Greenhaus & Powell 2006, p. 73). Two mechanisms describe the enrichment process: the ‘instrumental’ mechanism occurs when resources are shifted from one role to the other, with a direct instrumental effect ª 2016 John Wiley & Sons Ltd Journal of Nursing Management Work–family conflict and enrichment that enhances functioning in the second role; the ‘affective’ mechanism occurs when extensive resources from one role increase the positive affect within this role that, in turn, fosters the functioning in the other one (Greenhaus & Powell 2006). Recently, research has indicated that WFE should be considered as important for both employees and organisations (Molino et al. 2013). Existing research shows that WFE is positively associated with jobrelated (Boyar & Mosley 2007, Shockley & Singla 2011), family-related (van Steenbergen et al. 2007) and health-related outcomes (van Steenbergen & Ellemers 2009). Moreover, scholars have found that some personality traits, including extraversion and positive affectivity, can influence WFE (Wayne et al. 2004, Michel & Clark 2009), and that organisational support can be one of the antecedents of WFE (Carlson et al. 2006). For these reasons, it seems important for organisations to understand not only how to reduce WFC, but also how to promote WFE (Bakker et al. 2011, Molino et al. 2013). Studies of the nursing profession have generally concentrated on WFC rather than WFE (Cortese et al. 2010). Simon et al. (2004) did fundamental work on this construct as part of the NEXT-Study. The study found high WFC scores in many of the European countries considered, the highest being in Italy. Recent studies also found a high level of WFC among Italian nurses, and showed that WFC was significantly associated with burnout, sleep problems and presenteeism (Camerino et al. 2010), as well as with job satisfaction and turnover intentions (Battistelli et al. 2013). Regarding studies of WFE in health-care organisations, Tummers and Den Dulk (2013) identified relatively high levels of WFE in a sample of Dutch midwives. The authors demonstrated that work alienation and work pressure negatively influenced WFE. Russo and Buonocore (2012) examined the relationship between WFE and organisational- and professional-related outcomes, showing that high levels of WFE were related to lower intentions to leave the nursing profession. Job demands, WFC and WFE Scholars have indicated that job demands are the main determinants of WFC (O’Driscoll et al. 2006, Molino et al. 2015). This study considered two specific job demands related to WFC in the literature: workload and emotional dissonance. Workload is a general type of demand consisting of having too much work to do and not enough time to do it (van Veldhoven & Beijer ª 2016 John Wiley & Sons Ltd Journal of Nursing Management 2012). Even though workload is a general job demand, a number of studies considered this variable in the specific case of samples of nurses and showed a positive relationship between workload and WFC (Cortese et al. 2010). The second job demand investigated here is emotional dissonance, a type of demand specific to people-oriented professions, which consists of a discrepancy between felt and displayed emotions (Bakker & Heuven 2006). Bakker and Heuven (2006) showed that emotional labour and emotional dissonance were linked to burnout, and studies of the nursing profession, as well as other fields, shed light on the link between emotional dissonance and WFC in jobs involving frequent contact with the public (Ghislieri et al. 2012). The link between demands and WFE has rarely been explored in the literature and is probably more complex. In fact, enrichment hinges mainly on job resources (Ten Brummelhuis & Bakker 2012), which help the individual to develop new resources that can positively influence life outside work. However, according to the job demands–resources theory (Bakker & Demerouti 2014), job demands can play an important role in fostering work engagement but may turn into job stressors when meeting those demands requires considerable effort from which the employee does not recover adequately (Meijman & Mulder 1998). In a similar way, high levels of demands that are not balanced by adequate resources could be related to lower enrichment. Work relationships, WFC and WFE In studies investigating the resources that can mitigate WFC or increase WFE, particular attention has been devoted to the formal and informal support that organisations can give their employees (Kossek et al. 2011). The term ‘family-friendly’ is widely used to denote organisations that show they are supportive of employees’ needs to accommodate work and family responsibilities by offering benefits to help them manage multiple life roles (Ghislieri & Colombo 2014). A number of studies have emphasised the importance of supportive management in reducing WFC (Cortese et al. 2010). In their survey of hospital employees, Odle-Dusseau et al. (2012) found that WFE significantly mediated the relationships between family supportive supervisor behaviour on the one hand, and organisational commitment, intention to leave and supervisor ratings of organisational support performance on the other. 3 C. Ghislieri et al. A recent study by Lembrechts et al. (2014), carried out to identify possible antidotes to WFC among hospital nurses, found that organisational support, lack of workload and the absence of overtime can reduce WFC, whereas the use of work–family policies does not. A construct that has been used widely to determine whether an organisation is generally supportive is perceived organisational support. Eisenberger et al. (1986), in their first definition of POS, suggested that employees develop a general perception about the degree to which organisations appreciate their contributions and care about their well-being. Perceived organisational support ‘is also valued as assurance that aid will be available from the organisation when it is needed to carry out one’s job effectively and to deal with stressful situations’ (Rhoades & Eisenberger 2002, p. 698). Lastly, previous research considered POS as a job resource, finding, for instance, that it had a direct and an indirect effect on extra-role behaviour via the mediation of work engagement (Sulea et al. 2012), and also buffered the impact of emotional dissonance on disengagement (Karatepe 2011). Lastly, a very recent paper found that a specific type of POS – that is to support people utilising their personal strengths at work – buffers the impact of workload and emotional demands on absenteeism (van Woerkom et al. 2016). Several studies investigated the relationship between POS and the work–family interface, intended as either WFC or WFE. To give some examples regarding ‘conflict’, Casper et al. (2002) found that POS lessened the harmful effects of WFC on commitment when conflict was bidirectional (i.e. when it was high in both directions). Dixon and Sagas (2007) found that WFC partially mediated the relationship between POS and job satisfaction. In a more recent study, Gurbuz et al. (2012) confirmed that POS had a negative relationship with WFC (measured with the Netemeyer et al. scale 1996), while role overload did not have a mediating effect on the relationship between POS and WFC. Regarding ‘enrichment’, investigations addressed the buffer effect of POS on the relationship between job performance on the one hand, and both FWE and family-to-work conflict on the other (Witt & Carlson 2006). McNall et al. (2011) found, as mentioned in the introduction, that POS had a strong positive relationship with WFE. Furthermore, in supportive work environments, individuals reported high WFE, regardless of the dispositional dimension (i.e. core self-evaluations). However, when POS was low, individuals high in core self-evaluations reported higher WFE than those low in that dimension. 4 While organisational support has attracted growing attention in the scientific literature, few studies addressed work–family backlash. This expression refers to the opposition, resentment, animosity or annoyance that workers perceive or receive from their supervisors or co-workers as a result of their efforts to balance their work and family lives or their use of family-friendly benefits (Korabik & Warner 2009, Colombo & Ghislieri 2014). Perceived work– family backlash can influence WFC and WFE, with an effect opposite to that of POS. To date, few studies have addressed the possible impact of this variable on issues associated with work–life balance (Ricotta et al. 2011). Specifically, the scant literature bears out a difference between supervisor backlash and co-worker backlash (Ricotta et al. 2011) when these variables are linked to WFC, even though the two dimensions are correlated, while there are no studies that link backlash to WFE. As regards the distinction between supervisor and co-worker backlash, studies on support also highlighted a difference between supervisor and colleague support (Cortese et al. 2010). Despite the high correlation between these two constructs, research showed that supervisor support reduces WFC perceptions more than colleague support. Moreover, perceived resentment from supervisors and colleagues could reduce the freedom to use work–family facilitations (Parker & Allen 2001) which, consequently, may foster WFC and reduce WFE. Based on the scientific literature discussed above, this study tested the following hypotheses, all of which applied after controlling the effects of gender and working hours per week: H1. Job demands (H1a workload; H1b emotional dissonance) are positively related to WFC. H2. Work–family backlash (H2a. supervisor backlash; H2b. co-worker backlash) is positively related to WFC. H3. POS is negatively related to WFC. H4. Job demands (H4a. workload; H4b. emotional dissonance) are negatively related to WFE. H5. Work–family backlash (H5a. supervisor backlash; H5b. co-worker backlash) is negatively related to WFE. H6. POS is positively related to WFE. ª 2016 John Wiley & Sons Ltd Journal of Nursing Management Work–family conflict and enrichment Method Participants and data collection procedures Participants were nurses working in a hospital in the north of Italy. The organisation was divided into four working areas: medicine, surgery, intensive care and maternal and child health. A self-reported questionnaire was sent to the 942 nurses working in the hospital. The overall response rate was 55.1%, a value that is moderately low, but in line with other studies on nursing (VanGeest & Johnson 2011). After data cleaning, 500 respondents remained in the final sample. The hospital board of directors authorised the study. The participants signed an informed consent form, which researchers distributed to the nurses along with the questionnaires. To guarantee anonymity, respondents returned the questionnaires in drop-boxes provided by the hospital management. A cover letter attached to the questionnaire described the measures taken to guarantee anonymity, the voluntary participation and provided guidelines for filling out the questionnaire. Of the 500 respondents, 84.00% were women with an average age of 44.09 years (SD 7.06); 64.20% had a high school diploma, while 22.60% held a bachelor’s or master’s degree. Mean job tenure was 18.93 years (SD 9.56) and most respondents had a full-time job (82.20%) with an open-ended employment contract (96.00%) for about 35.01 hours per week (SD 5.17). Regarding working areas, 35.10% of the respondents worked in intensive care, 33.30% in medicine, 23.00% in surgery and 8.60% in maternal and child health. Measures All the measures used in this study were adapted in Italian and/or used in previous Italian studies. Work–family conflict was assessed with the Italian version (Colombo & Ghislieri 2008) of the five-item scale developed by Netemeyer et al. (1996) using a six-point frequency scale (1 = never, 6 = always). An example item was ‘The amount of time my job takes up makes it difficult to fulfil family responsibilities’. Cronbach’s alpha of this scale was 0.89. Work–family enrichment was measured using three items (Ghislieri et al. 2011). An example item was ‘At work I feel a sense of accomplishment and this helps me to be a better family member’ (1 = strongly disagree, 5 = strongly agree). Cronbach’s alpha was 0.85. ª 2016 John Wiley & Sons Ltd Journal of Nursing Management Workload was measured by four items taken from Bakker et al. (2004) and used in a previous Italian study (Molino et al. 2013). An example item was ‘How often do you have to work extra hard in order to reach a deadline?’ (1 = never, 5 = always). Cronbach’s alpha was 0.79. Emotional dissonance was assessed with four items (Zapf et al. 1999) used in a previous Italian study (Ghislieri et al. 2012). An example item was ‘Display positive emotions while feeling indifferent’ (1 = never, 6 = always). Cronbach’s alpha was 0.84. Supervisor backlash was assessed using six items (Ricotta et al. 2011). An example item was ‘Supervisors make negative comments if someone benefits from tools aimed at supporting work–family balance’ (1 = disagree, 4 = agree). Cronbach’s alpha was 0.91. Co-worker backlash was assessed using six items (Ricotta et al. 2011). An example item was ‘Co-workers make negative comments if someone benefits from tools aimed at supporting work–family balance’ (1 = disagree, 4 = agree). Cronbach’s alpha was 0.90. Perceived organisational support was assessed on a seven-point agreement scale (1 = strongly disagree, 7 = strongly agree). Six items were used from an eight-item scale (Eisenberger et al. 1997, validated in Italian by Battistelli & Mariani 2011) because two of the original items presented lower correlations with the other items and would have decreased Cronbach’s alpha. An example item was ‘My organisation really cares about my well-being’. Cronbach’s alpha was 0.87. Data analysis Descriptive analyses, internal reliability of the scales and correlations between variables were calculated using the PASW 18 statistical package (IBM, Armonk, New York, USA). The software was also used to test the relationship between the variables throughout hierarchical regression analyses. Specifically, the following variables were entered in the regression analysis: (1) at the first step, gender and working hours as control variables, (2) at the second step, workload and emotional dissonance as job demands that are the main predictors of WFC and can also be important in the enrichment process (Grzywacz & Marks 2000, Tement & Korunka 2015); the two dimensions of work–family backlash – both supervisor and coworker backlash; POS as a job resource based on positive work relationships, mainly associated with enrichment. 5 C. Ghislieri et al. Table 3 shows the results of hierarchical multiple regression with WFE as the dependent variable. The model shows no relations with gender and working hours per week at either the first step (corrected R2 0.01) or the second step (corrected R2 0.18). At the second step, workload and emotional dissonance have a negative low relation with WFE: b = 0.10 for both job demands. Perceived organisational support has a positive high relation with WFE (b = 0.34). No relations were found with either work–family backlash dimension (supervisor and co-worker). Results Table 1 shows descriptive statistics, reliability and correlations among all variables. Analysis shows a negative correlation between WFC and WFE (r = 0.28). Work–family conflict presents positive correlations with both job demands (workload, r = 0.28; emotional dissonance, r = 0.36), supervisor backlash (r = 0.30) and co-worker backlash (r = 0.19); moreover, the results show a negative correlation between WFC and POS (r = 0.28). Work–family enrichment shows negative correlations with both job demands (workload, r = 0.21; emotional dissonance, r = 0.20), both backlash dimensions (supervisor, r = 0.19; co-worker backlash, r = 0.09), and a positive correlation with POS (r = 0.36). Of the two control variables, working hours per week presents negative correlations with female gender (r = 0.22), co-worker backlash (r = 0.12) and POS (r = 0.15), as well as a low positive correlation with WFC (r = 0.10). Gender does not show other significant correlations. Table 2 shows the results of the hierarchical multiple regression with WFC as the dependent variable. At the first step (corrected R2 0.01), working hours per week shows a low positive relation with WFC (b = 0.11); gender shows no relation with WFC. At the second step (corrected R2 0.19), the control variables (gender and working hours per week) do not show any relation with WFC. As for job demands, both workload (b = 0.12) and emotional dissonance (b = 0.22) have a positive relation with WFC. As for the variables linked to work relationships, of the two backlash dimensions only supervisor backlash has a positive relation with WFC (b = 0.14), no relations were found with co-worker backlash; POS has a negative relation with WFC (b = 0.13).

The study also considered the relationships of WFC and WFE with two job demands, workload and emotional dissonance. Regarding H1, the results confirmed that job demands were potential predictors of WFC, in line with other studies on this subject (O’Driscoll et al. 2006, van Veldhoven & Beijer 2012). In particular, emotional dissonance was important in work-tofamily interactions: the effort involved in displaying emotions at work that differ from those that are really felt might cause spillover effects in other life domains, confirming results that were also found for other professions (Emanuel et al. 2014). H2 was partially confirmed. The results of multiple regression showed that only supervisor backlash was related to WFC. Therefore, potentially problematic situations might arise, above all in the relationship with the supervisor, when the need to balance work and family responsibilities was not given due consideration and attracted criticism and resentment, if not outright hostility (Korabik & Warner 2009, Colombo & Ghislieri 2014). Lastly, H3 was also confirmed: POS was negatively related to WFC (cf. Gurbuz et al. 2012). Regarding WFE, H4 was confirmed: both job demands (workload and emotional dissonance) were negatively related to WFE, in line with previous studies that found job demands as predictors of WFE in ª 2016 John Wiley & Sons Ltd Journal of Nursing Management heterogeneous samples (Grzywacz & Marks 2000, Tement & Korunka 2015). H5, on the other hand, was not confirmed: work– family backlash (neither supervisor nor co-worker backlash) was not related to WFE. Thus, it seems that WFE was not affected by negative aspects of the relationship, but was heavily influenced by the support received in the organisation. Although some job demands showed negative relationships with WFE, also in Italian studies that considered the nursing context (e.g. working hours per week; Ghislieri et al. 2011), WFE was mainly associated with job resources, particularly the support received from supervisors and colleagues. This aspect was congruent with the contribution by Greenhaus and Powell (2006), who highlighted, in particular, the improvement process due to resources from the work domain and reported positive relationships between WFE and a supportive and flexible work environment, networking in the organisation and acceptance by peers. Moreover, also in this study, the support aspect of the job seemed to be particularly able to foster enrichment. H6 was in fact confirmed: POS showed a strong, positive and significant relationship with WFE. This result was in line with the finding by McNall et al. (2011), who demonstrated that POS was a significant antecedent of WFE. Furthermore, the authors showed that respondents who perceived high POS reported higher levels of WFE, regardless of other variables, such as the personality dimension of core self-evaluations. The latter variable, however, was significantly related to WFE at low and medium levels of POS. Since POS ‘serves an important socioemotional function’ (Rhoades & Eisenberger 2002, p. 710) and has a strong positive relationship, for instance, with a positive mood, we might hypothesise that this variable powered the affective path toward enrichment (Greenhaus & Powell 2006). Nurses who felt more support from their organisation perceived higher positive emotions toward their job that, in turn, allowed them to perceive higher positive emotions in their family role. Conclusions The study addressed work–family balance in the nursing profession, considering both WFC and WFE. With regard to WFC, the study confirmed the important role of job demands, but also indicated that POS can have a direct impact on mitigating WFC (Gurbuz et al. 2012), whereas supervisor backlash can potentially intensify WFC. 7 C. Ghislieri et al. In relation to WFE, the role of POS appeared to be crucial (McNall et al. 2011), which seemed to enable people to see their jobs as an experience that generates resources, which could improve the quality of personal and family life. Although the study did not compare this element with formal aspects and concrete solutions, it nevertheless pointed to the importance of perceptions about the quality of support received from the organisation. The study is therefore a contribution to the literature in this area as few studies to date have considered both conflict and enrichment among Italian nurses and explored the influence of work relationships on these outcomes. However, it also has certain limitations. First, participants were nurses at the same hospital. Comparison with other hospitals, and in other regions, would be advisable in future research. Moreover, it is also possible that our findings were influenced by cultural characteristics that are specific to Italy. For this reason, it would be instructive to replicate the study in other cultural contexts (Biggio & Cortese 2013, Cortese 2013). Moreover, the cross-sectional research design relying on self-reported data means that results may be affected by common method variance, and an unequivocal interpretation of the causal relationships is therefore not possible (Conway 2002, Podsakoff et al. 2003). Future work should combine selfreported data with measures from other sources or other observers (e.g. supervisors and/or co-workers) and employ longitudinal designs (Polit & Beck 2004). Lastly, the relationships with supervisors and coworkers should be investigated in greater depth to determine how they are linked to work–family balance, and how they may both help and hinder it. Preliminary qualitative studies, particularly in-depth interviews, would also prove useful for this purpose. Implications for nursing management Action on the dimensions that could mitigate WFC and increase WFE (workload, emotional dissonance, supervisor backlash and POS) should be taken at individual, team and organisational levels. Before describing these actions, it is important to underline that they do not always call for major financial outlays: targeted investments should also be made on initiatives focusing on communicational, relational and cultural dimensions. Actions at the individual level are mainly those aimed at reducing workload perceptions through the ability to manage the workload itself. The focus should be on perceptions, since reducing the quantity of work tasks is not practicable nowadays, partly because of the hiring freeze caused by the contemporary economic crisis that has increased duties, shifts and time pressure (Cortese 2013). With regard to this, it is important to consider that having greater autonomy and being more aware about responsibilities, aims and priorities at work could help nurses to manage their job activities and to decrease workload perceptions (Zito et al. 2016). Measures to reduce emotional dissonance can be taken at both individual and team level. In particular, the study’s findings indicate that it is essential to devote attention to the emotional commitment and demands of the hospital environment where nurses exercise their profession. Individual training initiatives designed to help nurses to develop coping skills and to gain an appropriate emotional distance from their job could contribute to lightening this burden. In the same way, small group counselling for current teams should make members capable of giving mutual support (Pizam 2004). In particular, this support could be achieved by providing an opportunity Table 4 Three levels of nursing management actions and related expected outcomes Individual level Actions Target variables Higher autonomy in job activities More awareness about own working priorities, tasks and goals Individual training initiatives Decreasing workload perceptions Decrease of WFC Increase of WFE Decreasing emotional dissonance Decrease of WFC Increase of WFE Decrease of WFC Decreasing supervisor backlash Team level Counselling and coaching for nursing directors and head nurses Teamwork counselling Organisational level Teamwork training initiatives Introducing work–family benefits Decreasing supervisor backlash Increasing POS 8 Decreasing emotional dissonance Expected outcomes Decrease of WFC Increase of WFE Decrease of WFC Decrease of WFC Increase of WFE ª 2016 John Wiley & Sons Ltd Journal of Nursing Management Work–family conflict and enrichment to express the discomfort related to emotional dissonance during interactions with colleagues, thus gaining relief. At both the individual and team level, measures can also be taken to reduce supervisor backlash. In this respect, some efforts must be made to raise awareness of this problem among nursing directors and head nurses in order to ensure that they are not perceived as obstacles to the work–life balance – involuntary or otherwise – because of inadequate communication with the nurses they manage. It is thus important to help supervisors to engage in supportive behaviour that can be conducive to a family-friendly culture and to serve as an additional resource for increasing WFE (Molino et al. 2013). To this end, teamwork-training initiatives could also be accompanied by individual counselling, coaching and mentoring (Ghislieri & Gatti 2012). Lastly, as far as the organisational level is concerned, introducing work–family benefits and ensuring employees are aware of them can be useful in increasing POS. This will mean providing information and training on work–family balance, through counselling groups or hot lines, and developing solutions targeted at the expressed needs of employees (Amstad et al. 2011). Table 4 summarises the actions suggested in this paragraph, the target variables and the expected outcomes based on the study framework. Source of funding No funding was received for this study.
