Warner Bros.If you contemplate handing in your two weeks notice every time you talk to your boss, you're not alone. A new global poll from job search site Monster found that 32% of employees say they have a "horrible" boss, while only 15% say they have an "excellent" one. "A bad boss won't just jeopardize your career growth — they'll also negatively impact your personal life," says Lynn Taylor, a national workplace expert, author, and leadership coach.
