The COVID-19 pandemic represents a traumatic event that has profoundly changed working conditions with detrimental consequences for workers’ health, in particular for the healthcare population directly involved in addressing the emergency. Nevertheless, previous research has demonstrated that traumatic experiences can also lead to positive reactions, stimulating resilience and feelings of growth. The aim of this narrative review is to investigate the positive aspects associated with the COVID-19 pandemic and the possible health prevention and promotion strategies by analyzing the available scientific evidence. In particular, we focus on the constructs of resilience, coping strategies and posttraumatic growth (PTG). A literature search was performed on the PubMed, EMBASE, Scopus, Web of Science, Google Scholar and Psycinfo databases. Forty-six articles were included in the literature synthesis. Psychological resilience is a fundamental variable for reducing and preventing the negative psychological effects of the pandemic and is associated with lower levels of depression, anxiety and burnout. At the individual and organizational level, resilience plays a crucial role in enhancing wellbeing in healthcare and non-healthcare workers. Connected to resilience, adaptive coping strategies are essential for managing the emergency and work-related stress. Several positive factors influencing resilience have been highlighted in the development of PTG. At the same time, high levels of resilience and positive coping strategies can enhance personal growth. Considering the possible long-term coexistence and consequences of COVID-19, organizational interventions should aim to improve workers’ adaptive coping skills, resilience and PTG in order to promote wellbeing.

An increasing number of studies have demonstrated that humor can impact interpersonal relationships in organizations and employee well-being. However, there is little evidence coming from intervention studies in organizational settings. In response, we developed a training following the principles of positive psychology that aims at improving employees’ adaptive use of humor as a successful mechanism to deal with stress. In this study, we assess the effectiveness of such training and its impact on employee well-being. Results from this one-group intervention study in an emergency ambulance service (N = 58) revealed that the participants reported higher levels of cheerfulness (Z = −3.93; p < 0.001) and lower levels of seriousness (Z = −3.32; p < 0.001) after being exposed to the training. Indeed, the participants reported lower scores on psychological distress after the training (Z = −3.35; p < 0.001). The effect size of the training was medium (r = 0.31 to 0.36), suggesting that interventions to improve adaptive humor at work can be a useful resource to deal with workplace stress and foster employee well-being. These results may have interesting implications for designing and implementing positive interventions as well as for developing healthy organizations.

Research about harmonious passion as a personal resource that can have a protective effect in situations of stress and burnout is scarce but growing. Considering the job demands-resources (JD-R) model, the present study aims to address the above gaps by exploring the moderating role of harmonious passion at work in the relationship between burnout (physical fatigue, cognitive weariness, and emotional exhaustion) and intrinsic job satisfaction. The study sample consisted of 748 workers from service organizations (front-line employees) in southern Spain (Mage = 35.51, SD = 10.06, 52% women). Using statistical program R (R Core Team, 2022), the results of the regression models showed the moderating role of harmonious passion on the negative relationships between physical fatigue and intrinsic job satisfaction. In particular, at high levels of physical fatigue, employees with high scores on harmonious passion at work presented higher levels of intrinsic satisfaction compared with employees with low passion at work. That is, although service employees have high levels of physical fatigue, when they are passionate, they still possess satisfaction with their work. Therefore, our findings extend the JD-R theory by considering harmonious passion as a motivational resource that reduce feelings of burnout in service employees. Hence, it shows the importance of promoting the autonomous internalization of work, (through, i.e., job enrichment), which allows the development of harmonious passion at work and, therefore, increasing intrinsic job satisfaction.
