A growing body of empirical evidence shows that occupational health is now more relevant than ever due to the COVID-19 pandemic. This review focuses on burnout, an occupational phenomenon that results from chronic stress in the workplace. After analyzing how burnout occurs and its different dimensions, the following aspects are discussed: (1) Description of the factors that can trigger burnout and the individual factors that have been proposed to modulate it, (2) identification of the effects that burnout generates at both individual and organizational levels, (3) presentation of the main actions that can be used to prevent and/or reduce burnout, and (4) recapitulation of the main tools that have been developed so far to measure burnout, both from a generic perspective or applied to specific occupations. Furthermore, this review summarizes the main contributions of the papers that comprise the Special Issue on “Occupational Stress and Health: Psychological Burden and Burnout”, which represent an advance in the theoretical and practical understanding of burnout.

Purpose – The purpose of this paper is to explore the relations of authentic leadership (AL) with employee knowledge sharing behavior and intervening processes. Design/methodology/approach – A correlational study is presented with a sample of 562 workers belonging to diverse Spanish organizations. Findings – The results obtained by means of multiple regression analysis showed positive associations of AL on employees’ knowledge sharing behavior. Specifically, the effect on these employee behaviors was fully mediated by the group innovation climate, and partially by their identification with the workgroup. Research limitations/implications – Future works should study this association in depth and examine possible differential relationships of AL on diverse types employee knowledge, explicit, and implicit, proposed by Nonaka and Takeuchi (1995). Practical implications – The study indicates the type of leadership that should be developed in organizations, and the type of processes and environments to foster in the work units to stimulate acts of sharing knowledge among the members. Originality/value – This is the first study examining innovation group climate and workgroup identification as mediators between AL with employee knowledge sharing behavior.
