I am coming back to University and will be beginning my student job again where I (and every other student) only work Saturdays and Sundays. I requested a day off three weeks in advance and was met with hostility, and a threat to fire me? I ended up realizing that this work environment will not be suitable for me, and offered to be let go. However, she has done a complete 180 after I expressed this. I honestly just want to quit gracefully at this point. Any advice for me?
