Although expressions of anger may have a few benefits (for example, Daan Van Knippenburg has shown that some followers respond favorably to them, and work by Stanford University’s Lara Tiedens demonstrates that in some cases showing anger can make you look more powerful or competent), on the whole, studies have found that negative emotions generally cause managers to be seen as less effective. Kind leaders do small things to show they care about their staff as people, not just employees.
