Competitive employer positioning through career path analysis: the case of the Swiss nursing sector

Based on the theoretical and empirical groundwork of WCS across healthcare institutions, this study provides generic strengths-and-weaknesses profiles for major types of healthcare employers using a holistic inferential statistical approach.

Following secondary analyses of career statements originating from the nurses at work study [5], voluntary employer changes of nurses were assessed by first linking the various RQs to different types of left employers and, second, to use these RQs to predict the likelihood of different employer types being the follow-up employer. Thereof, we created the competitive strengths-and-weaknesses profiles for the largest types of nurses’ employers in terms of attraction (pull factors) and attrition (push factors) of nurses. Irrespective of queries on firm-specific branding and business strategy, practical strategic implications for each profile are derived.

Besides practical conclusions, the study advances the academic debate on institution-specific effects in the health sector by adding a causal perspective on the competing relationship between the left and subsequent employer in voluntary turnover. Furthermore, by theorising and measuring the effect of organisational context on turnover, we address a research gap in turnover research in the nursing literature [6].

Studies that explain nurse turnover have applied conceptual models and theories that consider a wide range of variables involved at different stages leading up to voluntary turnover [6]. However, although studies in the field of general management have conceptualised voluntary turnover across the individual, workgroup and organisational analysis levels, researchers in the nursing field have mainly focused on studying turnover at the individual analysis level [6, 7]. Therefore, research has suggested integrating more theory from general management literature and other fields to build more integrated and powerful conceptual models studying nurse turnover [6, 7]. Thus, our conceptual and theoretical framework relates to various variables, discussing individual RQs depending on the type of employer that varies in size, activity field and ownership at the organisational and macroeconomic levels. In reference to an integrated conceptual turnover framework such as the Integrated Turnover Model proposed in previous research, the assessed RQs and organisational types are found at the first stage (related to the nature of the job) and the second stage (organisational context, person–environment context and job attitudes) [6, 7].

Our study aims at examining the variance in turnover reasons due to workplace differences across organisational types to advise on employer positioning in the labour market rather than explain voluntary turnover per se. Thus, we use theories that provide an explanatory foundation for the variance in turnover reasons, at an organisational and macroeconomic level.

Empirical studies of workplace differences across different healthcare employers often focus on one-dimensional comparisons such as for-profit versus non-profit hospitals or stationary versus ambulant practices and therefore lack a holistic theoretical framework to compare workplace and turnover variables across a wider spectrum of organisation types.

Supporting our aim to compare a greater range of institutions characterised across multiple dimensions, we consult a broader theoretical framework which respects the practical nature of the categorisation but examines underlying definitory variables.

Public hospitals, private for-profit hospitals, socio-medical institutions such as nursing homes (SOMEDs), home care services, private medical offices and general practitioners and non-profit organisations (NPOs) are the main types of employers for nurses in Switzerland. This categorisation is based on bundled variations in organisational size, activity type, and ownership and goal systems, which can therefore be regarded as mediators of institutional differences. Hence, a combined view on theories and concepts, as outlined in Table 1 [8], helps to comprehend potential differences in perceived workplace conditions across healthcare institutions.

Previous comparative research of WCS across various institutions can be presented well following the structure of the theoretical discussion. Studies comparing organisations of different sizes show that working with larger healthcare employers, such as hospitals, is associated with more work strain and burnout, less autonomy and participation, and more regulation and burnout [34‐38].

Comparison studies of work settings across various activity types found that nurses working with challenging patients, typically in long-term care (i.e. SOMEDs), experience more stress and burnout [39, 40], but show more organisational commitment and higher professional identification [36]. Nurses working in outpatient or home care (i.e. home care services) in contrast to stationary care experience more autonomy, less regulation [36, 41], less work strain [39] and job satisfaction [36] and report higher meaning of work [42].

Research comparing workplaces with various types of ownership and goal systems found that nurses in the private sector, rather than the public sector, experience less administrative workload [27], less violence, more recognition [35], higher commitment [43] and greater job satisfaction [44]. However, nurses at public hospitals are more likely to be satisfied with salary and experience more job stability and employee benefits [45]. Nurses working at NPOs report less burnout [46] while earning more [47] and reporting greater well-being [48]. Generally, employees at private medical offices experience more autonomy and job satisfaction [32, 49].

Finally, using the introduced typology of the main six employers of Swiss nurses—public hospitals, private hospitals, private medical offices, socio-medical institutions, non-profit organisations and home care services—a recent comparative study shows that nurses working in private hospitals and public hospitals were less likely to experience autonomy and worktime flexibility than those working at smaller healthcare employers, whereas work at public hospitals, rather than at private hospitals, was associated with more stress, yet associated with more satisfaction with salary and advancement opportunities. Compared with other workplaces, SOMEDs were associated with more alienating WCS and lower job satisfaction, but with more participation and decision-making. In contrast, private medical offices were associated with a milder work environment and more social support than other institutions. Finally, working at NPOs and home care services was associated with higher degrees of autonomy, recognition, organisational commitment and job satisfaction [8].

Besides the assessment of WCS, nurse staffing and turnover were the focus of several studies, especially because they are linked to patient safety, health outcomes and mortality [52‐54]. With lower overall job satisfaction, the tendency for turnover is greater [57‐58]. More specifically, strong positive predictors of turnover or turnover intent in nursing are job stress, workload, emotional exhaustion and burnout [59‐66]. Further factors significantly linked to turnover are satisfaction with salary, career opportunity and professional development [64, 65, 67], organisational commitment [58, 63, 68], team culture, peer networks and leadership [59, 63, 65, 67, 69‐72], job characteristics such as non-nursing tasks [66], meaningful work [57], job complexity [63], perceived patient safety, sex (i.e. being male) [66], autonomy, participation and recognition [57, 63, 64].

Research on nurses’ turnover by type of institution is scarce compared to studies of turnover reasons in general. However, even if not differentiating between different RQs, several studies compare turnover intention or actual turnover across different employer types and settings. Nursing staff in nursing homes and hospitals is found to consider leaving nursing more often than those in home care [36], staff in hospitals more often considers leaving nursing than in primary outpatient care and nursing homes [73] and nursing staff in private hospitals considers leaving nursing to a higher degree than those working in psychiatric hospitals [74]. Moreover, nurses in nursing homes report greater intention to leave than nurses working in private or public hospitals [75]. Nurses in geriatric care are more likely to quit their job [76]. Finally, smaller work units, outpatient units and day care settings are associated with lower staff turnover [72]. Thereby, nurses working in home care may have a lower turnover propensity because workers in low-wage home care perceive more meaning and dignity. After all, it is supposed that nurses enter home care after quitting an alienating job, within or outside the healthcare industry [42].

We used data from the nurses at work study [5], a retrospective longitudinal cohort study of career paths of nurses who worked in Switzerland between 1970 and 2014. 15,301 nurses answered the online questionnaire between September 2014 and February 2015. The survey included questions about experienced WCS and RQs as well as it included a parallel section on simultaneous personal events, socio-demographic data and personality type.

To evaluate the pull and push characteristics of workplace criteria, we focused on voluntary staff turnover between the six main types of healthcare employers who employ roughly 90 per cent of all professional nurses, namely public hospitals, private hospitals, private medical offices, SOMEDs, NPOs and home care services [8]. After excluding movements within the same type of institution and movements from workplaces at which individuals worked less than one full day and/or had a tenure below one month, we analysed 4844 movements from 3011 nurses [see Additional file 1 for more details].

In the nurses at work study, respondents were asked to state why they left each of their former employers. The question ‘For what reasons did you leave this job?’ was only prompted if the turnover was voluntary, e.g. due to dissatisfaction with the job, due to a job offer or due to personal reasons. With the instruction ‘Please state any reasons that led you to leave the position’, the respondents were asked to select multiple RQs from a catalogue of 28 statements which contained items concerning the WCS as well as some items addressing reasons coming from outside of the organisation (e.g. job offer). Respondents could answer with yes or no or does not concern me in the case of a workplace could not be assessed in terms of this criterion. The catalogue of RQs concerning characteristics of the workplace or the tasks were, mostly, directly derived from validated variables addressing WCS [5].

Figure 2 indicates that nurses were more likely to work for a public hospital as a follow-up employer (strong pull arguments) when they quit their jobs because of low skill-use and advancement opportunities, when they wanted a professional change, when they were dissatisfied with salary and/or when they quit because of too many non-nursing tasks. In turn, these reasons were, as well, less indicated as RQ by nurses who left public hospitals (weak push arguments) and can therefore be considered type-specific strengths.

However, there are several deficits in WCS that were more frequently indicated as RQ and were less likely to act as arguments attracting new employees (Inability). For example, nurses who quit because of exhaustion and/or a poor work–life balance were more likely to have worked at a public hospital.

Nurses who left the former organisation because of low salary, too much non-nursing tasks, aggression and/or bad care quality were more likely to go to a private hospital. However, since care quality was also measured a strong push argument (Paradox), one may argue that private hospitals might be very heterogeneous regarding this aspect. Furthermore, nurses at private hospitals were more likely to come and go as a consequence of changing the place of residence.

What seems favourable to private hospitals is—moreover—that nurses were less likely to quit because of exhaustion, inconvenient work hours and low skill-use opportunity (Chance). Furthermore, work–life balance and professional identification were measured weak push arguments. But since these were also less likely to pull nurses towards private hospitals (Irrelevance), it may suggest that nurses at private hospitals are not overly seeking increased professional identification or enhanced work–life balance, in the first place.

Nurses working at private medical offices were more likely to leave because they could not use their skills, had low advancement opportunities and did tasks that they considered to be non-nursing activities. They were also more likely to leave because of low self-actualisation and dissatisfaction with salary as well as lowered professional identification. Yet, these criteria were no weak pull arguments (Threat), what may indicate hidden disadvantages or heterogeneity within the employer type. What can be considered—however—as important competitive weakness (Inability) concerns the inability to adequately satisfy nurses’ wish for change.

However, nurses at private medical offices were less likely to leave because of exhaustion and care quality, which can be considered as generally important reasons to leave a healthcare institution (see Additional file 4). Nevertheless, it could not be significantly measured that these also acted as strong pull factors (Chance). However, considered as a competitive strength—working as a strong pull argument while being a weak push argument (Prevalence)—are work hours. Finally, work–life balance is considered a strong pull argument, as well. That moving to a new house was located in the field Irrelevance field implies that nurses at private medical offices are either willing to accept longer distances between their home and their workplace or that they change their place of residence less frequently.

In comparison to other nurses, it was more likely for SOMED employees to leave the organisations because of harsh WCS captured in several criteria. This was also reflected in the competitive disadvantage (Inability) that SOMEDs seemed to lack on providing interesting job offers and hence were losing nurses to more appealing workplaces. Moreover, that moving to a new house was measured a strong pull factors suggests that nurses are more likely to be urged to work for SOMEDs.

Looking at further strong pull factors of SOMED workplaces, we paradoxically observed that the factors like exhaustion, care quality and superiors—while strongly pushing nurses away from SOMEDs—also were more likely to attract nurses (Paradox). This may either suggest that there is a sub-segment of SOMED workplaces that offers good conditions regarding these aspects or that nurses have false expectations towards theses specific WCS at SOMEDs.

NPO workplaces were more likely to attract nurses with a wish for change of work content while still working as nurses (Prevalence). Additionally, NPOs seem to prevail in providing interesting jobs, with much autonomy and participation (e.g. self-actualisation), although the criteria were yet located in the field of Chance. This implies that human resource management (HRM) at NPOs should stress these aspects more in their communication measurements to make them strong pull arguments. That personality and distinct motivational patterns could play a crucial role in attracting NPO nurses is supported by the irrelevance of factors that were of central interest in other employer profiles: salary, advancement and care quality.

In comparison to other nurses, nurses in home care services were not more likely to quit because of a specific reason, except because of inconvenient work hours. The fact that it was at the same time measured a strong pull factor (Paradox) is explainable by the ambivalent nature of the criterion (need variance). Like private medical offices, home care services offer shifts that clearly differ from hospitals (e.g. less night shifts needed).

Moreover, nurses who quit their former employers because of exhaustion, team-related aspects, care quality and lack of self-actualisation were more likely to choose home care services as their follow-up employers. The latter two criteria were, in addition, also measured weak push arguments making them strong competitive advantages (Prevalence) which seems even more favourable since these factors are generally rather common RQs (see Additional file 4).

In the rising competition for well-trained employees, nurses choose their follow-up employer deliberately according to criteria they ascribe to specific types of organisations. The turnover profiles presented in this article not only show that there is need for competitive agility but reveal, as well, where different types of employer should begin to improve and contrast, independently from their firm-specific branding or their business strategies. Depending on the position of workplace criteria in the specific competition-oriented diagram, employers may use the generic strategic HRM and employer branding recommendations suggested in Additional file 2. Criteria located in the Prevalence field are strong competitive advantages and can be communicated highly credibly to attract nursing workforce. Opposed to these, criteria in the Inability field are type-innate weaknesses which should be supervised carefully. Although HRM may never turn them into competitive advantages, these weaknesses should be enhanced to an acceptable level to reduce turnover. Criteria located in the Paradox field need further analysis since they underlie effects of either high workforce sensitivity, workforce heterogeneity or distorted employer perceptions on the labour market. Criteria allocated in the Irrelevance field are comparatively less involved in both nurse turnover and attraction. Hence, in competitive comparison, these criteria do not ask for immediate treatment by the HRM. However, criteria which reach significance either in their competitive push or pull dimensions but not on both indicate either positive or negative branding potential in one dimension, which should be addressed appropriately.

As the results bring more transparency to the nurses’ labour market and present the push-and-pull factors of major groups of health employers, this study may interest human resource management and employer branding professionals, support nurses in their career decisions and guide political and economic representatives of specific types of employers or nurses in Switzerland (i.e. professional associations and industry organisations) in their discussion of nurses’ WCS.

Although healthcare systems and labour markets differ across countries, our findings may be relevant for future research and HR managers abroad. After all, the discussed theoretical effects of institutional characteristics such as size, activity field and goal system are less bound to the political and socio-economic context. Moreover, the basic typology of major nurse employers may be found worldwide (hospitals, doctor’s offices, home care services and for-profit vs. non-profit offices). Furthermore, although correlations for specific variables involved in turnover decisions vary across countries and therefore hint at the importance of national contexts [80], similar outcomes and unidirectional effects for key predictors of turnover intention, such as job satisfaction, stress or burnout, are shown in literature reviews and cross-country studies of nurse turnover and working conditions such as RN4CAST or the NEXT study [52, 61, 80‐82].

Our research has some limitations. The surveyed sample may suffer self-selection bias and therefore lack representativeness because a sampling frame such as a registry of professional nurses was not available. Furthermore, while RQs were surveyed with each left employer, the questionnaire did not address the reasons why a certain employer was joined. This limitation was overcome using implicit pull factors as described earlier. Moreover, although the survey considered several RQs, the literature suggests further unassessed reasons for a voluntary turnover that could account for additional variance in career decisions. For example, nurses may be pulled out of the organisation by former peers and join them to another [6, 83].

We introduced a method to map results based on inferential statistical analyses, which can be adapted to any competitive field and extended with any control variables. Furthermore, the approach offers high automation potential for career platforms such as LinkedIn, which have already implemented analytics for organisations to identify recruitment competitors based on employee turnover. Surveying push-and-pull factors may result in the automated creation of competitive employer profiles online.

Future research may examine employer changes qualitatively and evaluate individuals’ expectations and experiences before and after the change. Moreover, as this study is limited to previous and follow-up employers only, future studies may explore the career paths of nurses across various healthcare employers holistically to shape employer branding with a better understanding of what nurses seek in their long-term careers.

The analysis revealed imperfect transparency in the applicants’ market regarding WCS with specific employers, which can be both useful and unfortunate for HRM. Moreover, the results indicate that different personality types attracted by specific employer types relativises the importance of certain WCS and their involvement in career decisions, which needs further research.

The nurse data were collected as early as 2014; hence, timely representativeness may be limited. However, because of the large sample size and data covering careers ranging back decades, our findings may rely on more structural and innate characteristics in the health sector and labour market while having relativised short-term changes and extraordinary events to insignificancy. Underlying theories have been proven valid over time and career decisions are affected by long-term experiences [84]. Finally, studies and literature reviews from different decades have shown the persistence of the main challenges and key factors associated with nurse staffing, turnover and working conditions, such as stress, burnout and organisational commitment as key predictors of turnover intention [81, 85, 86].

Finally, the competitive positioning of nurses’ employers in other countries may be assessed in future studies, providing more information about the robustness of the competitive push-and-pull profiles of employers across different healthcare systems, political and economic environments, hospital and professional standards and work regulations.
