Organisations are becoming increasingly aware of the importance of employees in gaining and maintaining competitive advantage. The happy worker–productive worker thesis suggests that workers who experience high levels of well-being also perform well and vice versa; however, organisations need to know how to ensure such happy and productive workers. The present review and meta-analysis identifies workplace resources at the individual, the group, the leader, and the organisational levels that are related to both employee well-being and organisational performance. We examine which types of resources are most important in predicting both employee well-being and performance. We identified 84 quantitative studies published in print and online from 2003 to November 2015. Resources at either of the four levels were related to both employee well-being and performance. We found no significant differences in employee well-being and organisational performance between the four levels of workplace resources, suggesting that interventions may focus on any of these levels. Cross-sectional studies showed stronger relationships with well-being and performance than longitudinal studies. Studies using objective performance ratings provided weaker relationships between resources and performance than self-rated and leader/third-party-rated studies.

Transformational leaders employ a visionary and creative style of leadership that inspires employees to broaden their interest in their work and to be innovative and creative. There is some evidence that transformational leadership style is linked to employee psychological well-being. However, it is not clear whether this is due to (1) a direct relationship between leadership behaviour and affective well-being outcomes, or (2) a relationship between leadership behaviour and well-being that is mediated by followers’ perceived work characteristics. (Such characteristics include role clarity, meaningfulness, and opportunities for development.) This study aims to extend previous work by examining the validity of these two mechanisms in a longitudinal questionnaire study. The study was carried out within the elderly care sector in a Danish local governmental department. A theory-driven model of the relationships between leadership, work characteristics, and psychological well-being was tested using Structural Equation Modelling. The results indicated that followers’ perceptions of their work characteristics did mediate the relationship between transformational leadership style and psychological well-being. However, there was only limited evidence of the existence of a direct path between leadership behaviour and employee well-being. These findings have implications for design, implementation, and management of efforts to improve employee well-being.

In recent years, there has been an increasing interest in how organizational-level occupational health interventions aimed at improving psychosocial working conditions and employee health and well-being may be planned, implemented and evaluated. It has been claimed that such interventions have the best chance of achieving a significant impact if they follow an intervention process that is structured and also includes the participation of employees. This paper provides an overview of prominent European methods that describe systematic approaches to improving employee health and well-being through the alteration of the way in which work is designed, organized and managed. The methods identified are the Risk Management approach and the Management Standards from Great Britain, the German Health Circles approach, Work Positive from Ireland and Prevenlab from Spain. Comparative analyses reveal that these methods all consist of a five-phase process and that they share a number of core elements within these phases. However, overall the five methods have not been thoroughly validated. To examine the validity of the core elements, we review them in the light of current research in order to support their appropriateness in conducting organizational-level occupational health interventions. Finally, we discuss where we still need more research to determine the working ingredients of organizational-level occupational health interventions.

Organizational-level occupational health interventions are often recommended when improvements in working conditions, employee health, and well-being are sought within organizations. Research has revealed that these interventions result in inconsistent effects despite being based on theoretical frameworks. This inconsistency indicates that intervention studies need to be designed to examine directly how and why such interventions bring about change and why they sometimes fail. We argue that intervention studies should include a process evaluation that includes a close examination of the psychological and organizational mechanisms that hinder and facilitate desired intervention outcomes. By drawing on existing intervention literature we present an evidence-based model containing three levels of elements that appear to be crucial in process evaluation. We describe how this model may be applied and developed in future research to identify better the mechanisms that link intervention processes to intervention outcomes.

A debate has arisen out of the need to understand true intervention outcomes in the social sciences. Traditionally, the randomized, controlled trial that answers the question of ‘what works’ has been considered the gold standard. Although randomized, controlled trials have been favoured in organizational intervention research, there has been an increasing interest in understanding the influence of context and intervention processes on the outcomes of such interventions. In the present critical essay, we question the suitability of trials and meta-analyses to evaluate the effectiveness of organizational interventions and we suggest that realist evaluation that seeks to answer the questions of what works for whom in which circumstances may present a more suitable framework. We argue that examining the content and process mechanisms through which organizational interventions are effective, and the conditions under which these are triggered, will enable us to better understand how interventions achieve the desired outcomes of improved employee health and well-being. We suggest that organizational intervention content and process mechanisms may help bring about the desired outcomes of improved employee health and well-being and that contextual factors determine whether these mechanisms are triggered.

The powerful positive results of implementing teamwork are not always achieved. It has been suggested that attempts to implement theories regarding teamwork do not always lead to those theories being put into practice, and as a result positive outcomes are not always found. The participation of employees in the development and implementation of an intervention may help to ensure that changes take place. In this longitudinal study (N=583) of teamwork implementation in Denmark we examined the links between pre-intervention working conditions and well-being, levels of participation in planning and implementation, employees' reports of changes in procedures, and intervention outcomes. Pre-intervention levels of autonomy and job satisfaction predicted the degree of employee participation in the planning and implementation of the intervention. Pre-intervention well-being and social support were linked directly to the degree to which employees reported changes in existing work practices concerning teamwork. In addition, participation and changes in work procedures were significantly associated with post-intervention autonomy, social support and well-being. The results indicate that employee participation in intervention processes is crucial in what appears to be an important association with perceived changes in procedures and, therefore, in intervention outcomes.
