Finding a boss you respect and who will respect you is critical for your career success. Otherwise, it can—and often will—lead to uncomfortable situations and toxic environments. Ultimately it just won't work,” says Lori Scherwin, founder of the New York City–based career coaching firm Strategize That. “You want someone who will actively develop you and cares about your career, not just what you will do for them.” When it comes time for evaluations and promotions, your boss’s input matters the most so you want someone who will advocate for you, give concrete feedback, and help you reach your goals.
