We describe how (positive) organizations can be enhanced from the framework of Positive Psychology, being healthy from a psychological point of view, as well as resilient in times of crisis and turmoil. Thus, Healthy & Resilient Organizations (HEROs) make systematic, planned, and proactive efforts to improve employees' and organizational processes and outcomes (Salanova, Llorens, Cifre, & Martínez, 2012). These efforts involve fostering healthy organizational resources and practices aimed at improving the work environment, especially during changing times. Despite its relevance in modern societies, research on how to develop HEROs is scarce. Therefore, in this article first we focus on its concept and the measurement, and then, we review the main research conducted on interventions to promote HEROs based on Positive Psychology from a collective (teams and organizations) and an individual (employee) point of view. Lastly, we develop a set of best practices on positive interventions in the organizational context.
