Do You Have a Toxic Boss? Here's How to Tell. There are seven types of toxic bosses, and it's important to learn how to deal with each of them.

The past year has tested leaders in ways they've never experienced before, and there's no sign that's going to change any time soon. Your boss might've handled the pandemic with grace, making work hours flexible to accommodate family responsibilities, scheduling weekly check-ins and making sure you're staying afloat. Or, they might've done the opposite.

An estimated three-fourths of American workers say their boss is their primary source of work stress, pandemic or no pandemic. But, how can you tell if your boss is actually toxic and taking a serious toll on your mental and physical health?

Harvard's Barbara Kellerman breaks down the seven types of toxic bosses in her book, Bad Leadership:

• The Incompetent Boss is unable or unwilling to do their job well.
• The Rigid Boss confuses inflexibility with strength.
• The Intemperate Boss lacks self-knowledge and self-control.
• The Callous Boss lacks empathy and kindness.
• The Corrupt Boss steals or cheats to promote their own interests.
• The Insular Boss is cliquish or unreachable.
• The Evil Boss causes pain to further their sense of power and dominance.
