I'm 19 and this is my second job. I work at a gas station, I originally worked evening shifts and was part-time but our overnight guy quit and they asked me to work his schedule instead. I agreed since Im a night owl so working at night was great, until now that they turned me into a full time worker, I never agreed to that and so I asked about just doing the 3 overnights and staying part time and they said no. I don't like confrontation since I always cross the line on what I say and my store manager acts like a teenager, I have felt like quitting but I can't seem to find another job that I'm willing to work until about 9 more weeks, I need help, what should I do?
Tl:dr I got moved to full time and my boss is a baby and I don't want to be full time
