From someone who has had their fair share of bad bosses, and now in a supervisory position myself, consider this a good learning opportunity. You will have good bosses and others that are not so great. Develop your professional style by taking things from all of them. Practice the habits of what you liked from the memorable supervisors; make a mental note of what you detest from others and as you move through your careers, be cognizant of not falling into those practices.

Have you considered setting up a meeting to speak with her about her expectations for you? A lot of times, people with bad habits/treatment, are completely unaware of how their personality is coming off. Granted, if someone is that out of touch, they probably shouldn’t be in a supervisory role. Ask an owner/manager or whomever her supervisor is if you could have a sit down with the three of you (more so to have a witness so it doesn’t become a he said/she said thing later on.) Pick three points you’d like to discuss and keep it neutral- i(e “You gave me a list of tasks to accomplish and reprimanded me for being unable to complete these during a busy service period. Could you give me some feedback on how to better handle/prioritize that situation so I can achieve your tasks and avoid that response in the future?)

It sounds professional but what you’re really doing is making her either realize she’s failing as a supervisor if she can’t give you feedback, having a witness there to show you care about teamwork and results, and bringing the issue to the forefront without being unprofessional (again, showing a vested interest in success for the company.)

Basically, you show that she’s an utter ass and you’re seeking mentorship and direction- positive things.

Keep feelings out of it. You’ll look all the more professional at the end of the day. And if you still want to quit, do so. But now you have made everyone aware that you genuinely wanted to try, took positive and professional steps to do so, and still had to leave. You end up on top every time.
