“Bad bosses require you to be on guard leading to a rise in stress hormone or cortisol levels. When you regularly get nervous or angry, this brings down serotonin or the relaxing hormone levels. Hence, the first thing you notice, when handling a tough boss, is disturbed sleep and tiredness,” states Hvovi Bhagwagar.

“One of the most popular theories of psychology suggests that the way we respond to our boss is how we responded to our parents as children,” says Bhagwagar.
