Introduction
Nurses’ intention to leave work has become an increasingly urgent global issue [
1]. The World Health Organization’s report on the health workforce requirements for sustainable development goals predicts a shortage of more than 14.5 million healthcare workers by 2030, including 7.6 million nurses and midwives [
2]. The context of intention to leave work among nurses refers to thinking about, planning, and making decisions concerning the possibility of leaving the profession, leading to actual resignation at the last stage [
3]. When this process is not managed correctly, the loss of a trained nurse workforce can be quite costly for healthcare institutions [
4]. Nursing Solutions, Inc. (NSI) have found that a single hospital in the United States loses between 6.6 and 10.5 million dollars on average per year due to nurse turnover [
5]. One systematic review found that nurse turnover costs in Australia, South Korea, the USA, Brazil, and New Zealand are very high, ranging in amounts up to three times the average nursing salary [
4]. Another study reported that nurse turnover rates result in costs between 0.31 and 1.3 times the average nursing salary [
6]. Previous studies have shown that nurses’ intention to leave is associated with factors such as performance [
7], efficiency, profitability and sustainability of quality of care [
3,
8], patient quality and safety, practice environment [
9,
10], and increased working hours [
11]. And also, nurse turnover is reported to be related to quality of care [
12] and care outcomes in patients [
4], as well as job stress [
3], professional commitment, job satisfaction [
3,
10], burnout, emotional labor [
10], resilience and occupational stigma in nurses [
11]. As such, the management of nurse retention has become a strategic necessity.
Nurse turnover has increased significantly due to the COVID-19 pandemic. One meta-analysis study found that approximately one third of nurses have thoughts of leaving the profession [
1], while another study reported that one in five nurses consider leaving [
13]. Playing a critical role while working on the front lines, nurses have faced many challenges during the pandemic [
14]. They have been exposed to increased working hours, physical challenges such as fatigue and excessive amounts of stress, mental challenges such as feelings of burnout and deterioration of family integrity, social challenges such as role confusion, and institutional and managerial challenges such as lack of communication, lack of administrative support, and problems in the flow of information [
14‐
16]. These challenges have undoubtedly affected nurse performance, as well [
7,
17].
Performance is defined as the achievement of previously planned goals and objectives as a requirement of the job, as well as the fulfillment of assigned roles and responsibilities. In this context, Individual Work Performance (IWP) is evaluated according to three components [
18,
19]: task performance (TP) includes actions that achieve business goals (such as job-specific planning, organization, result-oriented behavior, and fulfillment of responsibility) [
19]; contextual performance (CP) includes behaviors that benefit the institution but are not included in the job description (such as interpersonal relationships, organizational citizenship, extra role performance, peer support, and team relations) [
20], and counterproductive work behavior (CWP) includes negative conduct that harms organization performance (such as disobedience, theft, drug use, and absenteeism) [
21]. Nurse performance is the main criteria for organizational achievement [
22]. The performance of nurses, who constitute the majority of human resources in health institutions, is essential to the achievement of positive patient, nursing, and organizational outcomes, as well as to the evaluation of the quality of healthcare services [
20,
23]. While nurse performance has become even more important during the pandemic process. On the one hand, the challenges experienced during the pandemic have reduced nurse performance [
24], while on the other, they have also forced nurses to increase their performance [
25]. This dilemma constitutes the focus of the present study. Nurse performance is a fairly broad concept [
26,
27].
Previous studies have found that challenges experienced during the pandemic have directly reduced nurse performance while increasing nurses’ intentions to leave the profession [
1,
3,
4,
13,
17]. However, no study has yet been conducted to comprehensively assess the impact of pandemic challenges (physical challenges, mental challenges, social challenges and institutional and managerial challenges) [
15]. On the other hand in a qualitative systematic review study conducted by Bahlman-van Ooijen et al. (2023), the motivations of nurses to leave the nursing profession were revealed through studies conducted between 2010 and 2023. Accordingly, the reasons that increase the motivation of nurses to quit were reported under four headings: (1) Challenging working environment: poor working conditions, inadequate salary and contract, lack of opportunities for career development, lack of support; (2) Emotional distress: work-related stress, great responsibility and fear of failure; (3) Disillusionment with the reality of nursing: nursing as the second best career option, inconsistency between education and practice, social image of nursing; and (4) Hierarchy and discrimination culture: feeling subordinate, bullying behavior [
28]. The additional challenges of the pandemic have exacerbated an already global shortage of nurses. Pandemics are unpredictable and their course can be volatile once they start. Similar processes can be experienced again as a result of pandemics with different names due to different reasons. In this context, it is unclear how health systems will respond when there is a shortage of nurses in health institutions. Therefore, retaining the nurse workforce, especially in pandemic situations, is of great importance in ensuring the continuity of quality and safe nursing care and protecting public health [
1,
9,
17,
29]. In this context, it was considered important to investigate the effect of the challenges experienced by nurses during the pandemic on their intention to leave work, as well as the role that nurse performance plays in this relationship.
Theoretical framework
This study’s model is based on Job Demand-Resource (JD-R) theory. JD-R theory separates the characteristics of a job into the categories of either job demands or job resources [
30]. Job demands refer to the physical, psychological, social and organizational/managerial aspects of work that require effort (work overload, stress, etc.). Job resources, on the other hand, are factors that help to achieve job-related goals, reduce demands, and promote growth and development (development opportunities, participation in decisions, etc.) [
31]. In other words, job demands include the job’s requirements, while job resources include opportunities related to the fulfillment of these requirements [
30]. The balance between increased job requirements and decreased resources leads to disadvantages such as work-family conflict, emotional exhaustion [
32], decreased nurse well-being [
33], and decreased organizational commitment [
34]. Therefore, maintaining a balance between job requirements and resources can prevent negative outcomes such as nurse turnover. This study focused on the mediating role of performance in the effect of nurses’ challenges during the pandemic on their intention to leave work.
The hypotheses were:
*Nurses’ TP mediates the effect of challenges experienced by nurses during the pandemic on their intention to leave work (H1),
*Nurses’ CP mediates the effect of challenges experienced by nurses during the pandemic on their intention to leave work (H2), and.
*Nurses’ CWP mediates the effect of challenges experienced by nurses during the pandemic on their intention to leave work (H3).
Discussion
The mediation effect helps to explain the effect of the independent variable on the dependent variable by another variable. It is a variable that helps to understand how and why the relationship between two variables occurs [
43]. This study examined the mediator role of work performance in the effect of the challenges experienced by nurses during the pandemic on their intention to leave work. The study’s model was based on JD-R theory, and all research hypotheses were supported. Despite the limited number of variables, the study examines more than direct relationships between variables. Simple bivariate analyses may not be enough to unravel the mechanism. Determining how the hypothesized relationship is influenced by other variables can be achieved with the advanced statistical methods used in the study. This study may allow future research to examine the variables that predict nurses’ turnover intentions in a single picture, identify their relationships and explore mediating effects.
According to the results, nurses’ TP was mediated by the effect of pandemic challenges on intention to leave work, supporting H1. TP showed a partial mediation role. The study’s results revealed that pandemic challenges it increases the intention to leave the work, and this effect decreased in nurses with high TP. This finding may be related to nurses’ result-oriented attitudes towards task responsibility, despite the various challenges faced by nurses during the pandemic. Varasteh et al. (2022) also reported that despite the presence of such challenges, nurses have taken their responsibilities to the profession and their colleagues seriously and therefore did not consider leaving their jobs [
29].
This study also found that nurses’ CP was mediated by the effect of pandemic challenges on intention to leave work, supporting H2. CP was found to play a partial mediating role. Considering the relationship of CP with factors such as team relations, peer support, and organizational commitment [
20], nurses who exhibit high commitment to their profession, colleagues, or organization may not want to quit their jobs, despite the presence of challenges. Kadiresan et al. (2015) and Maden Eyiusta (2015) have found that the developed commitment among employees reduces their intention to leave work [
44,
45]. In addition, previous studies have shown that includes dimensions such as interpersonal assistance and dedication to work, with CP associated with interaction with employees, positive thoughts, positive emotions, and satisfying and motivating behaviors experienced towards one’s own roles [
46].
This study determined that nurses’ CWP played a mediator role in the effect of pandemic challenges on intention to leave work, supporting H3. In this case, nurses’ CWP may have reduced their intention to leave work because of their motivation to either consciously and systematically protest, or to sabotage and harm the organization or its members. A study by Saad Saleh Ali and Abdelwahab Ibrahim Elsayed (2022) reported that organizational cynicism is a factor that increases the incidence of CVB s among nurses [
47]. However, one should not consider CWP s only within the context of physical harm. Other behaviors such as gossip, retaliation, condescension, absenteeism, lateness, early departure from work, and unnecessarily long breaks have also been identified as CWP [
48]. A study by Babaei Aghbolagh and Sattari Ardabili (2016) has found that nurses’ participation in environmental gossip reduces work anxiety and stress [
49]. In addition, it is important to distinguish between voluntary and involuntary absenteeism. Voluntary absenteeism refers to absenteeism under the control of the employee, while involuntary absenteeism refers to the opposite [
50]. If a nurse is unable to go to work for reasons beyond her/his control, arrives late, or leaves early, she/he is expected to perform better to compensate for such situations and her/his intention to leave the job may decrease. However, in cases of arbitrary absence from work, she/he does not make an effort to perform and may go as far as leaving the job. In this context, the correct evaluation of such behaviors may contribute to effective management.
Lastly, healthcare providers, especially nurses, need to be ready to intervene immediately when mass events occur that profoundly affect large populations, such as pandemics, wars, terrorism, natural disasters, etc [
51,
52]. In addition, nurses face various challenges (physical, psychological, social, institutional and managerial) at all stages of the process due to the suddenly increasing patient load in the healthcare system [
15,
53]. Regardless of the cause of the mass incident, it is vital to keep nurses in the system and to ensure that the nursing services provided to individuals are of high quality, safe and continuous. As Jabbur et al. (2021) stated in their study on the 2020 explosion in Beirut, what motivates nurses to stay at work and perform their nursing performance despite all the difficulties experienced may be related to their values such as professional sacrifice, self-sacrifice, and putting the lives and well-being of others before themselves [
54]. The vital role nurses play in responding to mass incidents, especially epidemics, and their experiences may enable them to learn from the past when faced with similar events once again. The results of this study, like the results of other studies in the literature on the difficulties experienced by nurses in mass incidents, may guide health managers and policy makers in developing strategies to improve nurse performance [
52‐
55].
Limitations
While this study has provided some important evidence, it also has limitations. This study used an online survey, which may have limited accessibility for people with less ability or inclination to use the internet. Therefore, using a printed questionnaire may yield different results. The use of snowball sampling may have limited access to some samples. Bias associated with giving the desired response may have skewed the results of the study. Variables were measured using self-assessment scales. The resulting data are subjective and depend on the honesty and openness of the participants. Future studies are recommended to conduct performance evaluations with the participation of nursing managers and/or patients. In addition, future clinical observational studies may result in more objective findings. The relationship between difficulties experienced by nurses during the pandemic, turnover intention, and performance deserves further investigation because performance cannot fully explain this relationship. Future studies could examine more variables to uncover the mechanism of this relationship. Another limitation of this study was its cross-sectional design and future studies are recommended to use longitudinal designs. Longitudinal designs may be more effective in revealing the causal link between variables. Finally, this study is limited to questionnaires with specific response options. Quantitative and qualitative methods (mixed method) could be used to obtain more objective and detailed data on performance. Finally, the findings of this study are limited to nurses who volunteered to participate in the study; those who declined participation may have different perceptions.
Conclusions and recommendations
This study determined that task-related, contextual, and CWP s play an important role in the effect of the challenges experienced by nurses during the pandemic on their intention to leave work. In addition, it was determined that CFNP, ILW, TP, CP and CWP had no significant effect on gender, marital status, age, total professional years, educational level, type of institution and unit of employment. This study’s results concerning the effects of the challenges experienced by nurses during the pandemic, as well as knowledge of the factors that reduce these effects, may guide managers in better planning and improvements when faced with similar events in the future.Identifying and improving the causes that reduce nurse performance is key to increasing nurses’ task and CP. Accordingly, in order to improve nurses’ attitudes toward their work, organizations should create healthy and safe work environments, as well as provide supportive and fair working climates. In addition, this study found that CWP reduced nurses’ intention to leave work. Further examinations of the relationships between CWP and different variables, using various and larger samples, are recommended. We also call on nurse researchers to study the effect of nurses’ CWP on organizational outcomes.
