A higher testosterone level does not always indicate well-being in men, according to a study at the University of Gothenburg. Muscle health and inflammation are linked to testosterone levels, but symptoms like fatigue and depression have weaker connections.
A new study by PSU researchers finds that abusive supervision can fundamentally alter how employees perceive their humanity, leading to severe burnout and decreased collaboration. In contrast, employees with a strong sense of self-efficacy are less susceptible to the dehumanizing effects of a toxic manager.
