In this article, we argue that changes in workplace characteristics over the last few decades may affect work relationships and call for adjustments in the traditional theoretical framework used to understand them. Since the last quarter of the 20th century, there have been theories regarding changes in labor relationships following technological, political, globalization, and economical changes. However, we examine the changes in light of psychological theories rather than labor or industrial approaches. We review four main areas where social exchange theory (SET) has been implemented, address recent changes that challenge the traditional SET perspective, and propose alternative models. We refer to these models as “hybrid” as they integrate traditional SET premises with new-era workplace characteristics. First, we describe several changes in workplace characteristics. Next, we review some of the most conventional applications of SET to work relationships. Finally, we critically examine whether this theory meets the requirements of work relationships in the new world of work and conclude by arguing that SET needs to be adjusted to reflect the assumption that frequent changes in employee and organizational characteristics in the new workplaces require similar frequent adjustments in exchange relationships.

a b s t r a c tWork stress has extremely significant consequences to the individual and to the organization (Barling, Kelloway, & Frone, 2005). This study examined the relationship between perceived work stress, burnout, satisfaction at work, and turnover intentions. We hypothesized that a positive relationship would be found between work stress and burnout, and negative relationships would be found between burnout and satisfaction, and between satisfaction and turnover intentions. The sample included 124 hospital physicians. As expected, all our hypotheses were corroborated. Structural Equation Modeling (SEM) found that beyond the assumed direct relationships, burnout partially mediated between work stress and work satisfaction, and work satisfaction partially mediated the relationship between burnout and turnover intentions. The paper reviews the theoretical consequences and suggests ideas for future research. © 2015 Colegio Oficial de Psicólogos de Madrid. Published by Elsevier España, S.L.U.

Estrés laboral e intención de abandono en médicos hospitalarios: el papel mediador del agotamiento y la satisfacción laboralPalabras clave: Estrés laboral Agotamiento Satisfacción laboral Intención de abandono Modelo de ecuaciones estructurales Mediación r e s u m e n El estrés laboral tiene consecuencias muy importantes para la persona y para la organización (Barling, Kelloway y Frone, 2005). Este estudio analiza la relación entre estrés laboral percibido, agotamiento (burnout), satisfacción laboral e intención de abandono. Planteamos las hipótesis de que habría una relación positiva entre estrés laboral y agotamiento y negativa entre este último y satisfacción y entre esta y la intención de abandono. La muestra estaba compuesta por 124 médicos de hospital. Según lo esperado, se corroboraron todas las hipótesis. El modelo de ecuaciones estructurales demostró que más allá de las supuestas relaciones directas, el agotamiento mediaba parcialmente entre el estrés laboral y la satisfacción laboral y esta mediaba parcialmente la relación entre agotamiento e intención de abandono. El trabajo revisa las consecuencias teóricas y propone ideas para la futura investigación. © 2015 Colegio Oficial de Psicólogos de Madrid. Publicado por Elsevier España, S.L.U.

Purpose Work-family conflict is a rapidly developing field of research, considering the changes that have occurred in the structure of the family and of work in recent years. The purpose of this paper is to put forward a wide theoretical framework that encompasses the relationships between organizational justice, organizational citizenship behavior (OCB), job stress, and the work-family conflict. The authors suggest an explanatory model that associates those variables. Design/methodology/approach The explanatory model was empirically examined by means of structural equation modeling. In all, 120 Israeli-Arab employees responded to the research questionnaires. Findings As hypothesized, organizational justice was found to relate positively to OCB, and stress was found to relate positively to the work-family conflict. However, contrary to the hypotheses, OCB was found to relate negatively to job stress and work-family conflict. Namely, the higher the OCB, the lower the job stress. Research limitations/implications Theoretical implications and suggestions for possible future research were advanced. Originality/value Organizations that want to avoid the negative implications of the work-family conflict should encourage OCBs, which reduce the workers’ job-related stress and consequently reduce the conflict between the realms of family and work.

Introduction: the choice of strategies to cope with stress has differential effects on individual and organizational outcomes (e.g. well-being and performance at work). This study examined to what extent individuals differing in their positive psychological resources (optimism, hope, self-efficacy and resilience) implement different strategies to cope with stress in terms of change, acceptance, or withdrawal from a source of stress in an organizational setting. Method: A questionnaire was filled out by 554 employees from different organizations representing a wide range of jobs and positions. Results: Structural Equation Modeling (SEM; χ 2 (7) = 27.64, p < .01, GFI = .99, NFI = .91, CFI = .93, RMSEA = .07) Conclusion: the results indicated that psychological resources (optimism, hope, self-efficacy and resilience) were positively related to coping by change and by acceptance and negatively related to withdrawal. The theoretical implications are discussed. Resumen Introducción: la elección de estrategias de afrontamiento al estrés, tiene efectos diferenciales en los resultados individuales y organizacionales (por ejemplo, el bienestar y el rendimiento en el trabajo). En este estudio se examinó hasta qué punto las personas que difieren en sus recursos psicológicos positivos (optimismo, esperanza, autoeficacia y resiliencia) implementan diferentes estrategias para hacer frente al estrés en términos de cambio, aceptación o retirada de una fuente de estrés en un entorno organizacional Método: 554 empleados de diferentes organizaciones que representan una amplia gama de puestos de trabajo y puestos respondieron un cuestionario. Resultados: modelado de ecuaciones estructurales (SEM; χ 2 (7) = 27.64, p < .01, GFI = .99, NFI = .91, CFI = .93, RMSEA = .07) Conclusión: Los resultados indicaron que los recursos psicológicos (optimismo, esperanza, autoeficacia y resiliencia) estaban relacionados positivamente con el afrontamiento por el cambio y por la aceptación, y negativamente relacionados con la retirada. Las implicaciones teóricas son discutidas.
