Due to its negative effects on both mental and physical health as well as employee work performance, burnout is widely recognized as an important issue in the working environment. Previous studies have consistently shown a negative correlation between a transformational leadership style and burnout. However, not many studies examined whether the emergence and effectiveness of transformational leadership depends on various organizational context characteristics, for example situational strength. The aim of this study was to examine the correlation between these variables and the moderating effect of situational strength on the relationship between transformational leadership and burnout symptoms. This study encompassed 638 employees selected by their superiors. The participants filled out an online questionnaire where they assessed the transformational leadership of their superiors, the situational strength in their workplace and self-assessed their burnout symptoms. The results show a significant negative correlation between transformational leadership and burnout symptoms, a significant negative correlation between transformational leadership and situational strength, and a significant positive correlation between situational strength and burnout symptoms. Also, the significant moderating effect of situational strength indicates that the relationship between transformational leadership and burnout symptoms is significantly stronger in weaker situations. These findings could be used in practice to encourage transformational leadership training for management as well as the creation of weaker situational strength within organisations.
