Stop trying to change people who should not be in their job. Some people feel they’re in the wrong job at the wrong company. Perhaps they believe that they were meant to be doing something else. Or that their skills are being misused. Or that they they’re missing something. If you have any sensitivity. You have a good idea who these people are. Even if you pick up only a tiny molecule of this vibe. ask them, “What if we shut down today? Would you be surprised, sad , or relieved?” More often than not, they will choose “relieved.” Take that as your cue to send them packing. You can’t Change the behavior of unhappy people so that they become happy. You can only fix the behavior that’s making the people around them unhappy.
