Dealing with disappointments at work can be really difficult, just as dealing with disappointments outside of work can sometimes pose a challenge. Feeling like you've been let down, however that might have occurred, can sort of make you feel unsettled, confused, or hurt. And though you want to believe that you and your boss are on the same team, when they disappoint you, it can sometimes seem like that's not exactly the case. But if your boss disappoints you in these ways, you need to leave your job, or at least consider what other kinds of options you might have to make sure that you're taking care of yourself and your career and not sacrificing too much in order to stay in the same place.
Oftentimes, under the best circumstances, you want to trust your boss and believe that they have your best interests at heart. But sometimes they do things that make you question that (or even seemingly prove to you that they definitely don't). If your boss disappoints you once or twice, you might not need to reevaluate your entire situation, but if they do certain things or continue to disappoint you again and again, it might be time to start looking for something new because it just may be time for you to move on to better things.
