it sounds crazy but what matters in the long run is what the boss says. she is the one you have to keep happy. right or wrong. she may be a crappy unhappy person, but she is in charge. it's work, and it isn't always a fun pleasant place. bosses can be jerks, and often are. the options are simple: continue working there, or leave.

you are fAirly new to the workplace and employment so it can seem like a crazy environment...my take on it is that other workers have found ways to work around this supervisor. you are very new. she may tolerate the older , long term staff, but since you are so new to the place, my guess is she will have low tolerance to you pulling the same tricks they do. if she says jump, my best guess is to ask "how high" and then do it. work isn't meant to be a joyous fun time..it is meant to produce the best results for the company..which is what this supervisor is trying to accomplish. so like I said...you can opt to tow the line and stay, or leave.
