We all know what managers do because we’ve all worked under at least one (if not many) over the course of our careers. And, boy, can they impact our lives – both at the office and personally. On one hand, a bad manager can torpedo morale and even drive us to seek a new job. Someone who is good at managing others, on the other hand, will inspire and motivate us. In the same way, managers – good and bad – directly impact our happiness at work (and in life).
