What would you do?

Hi ladies sorry if this may not be about sex or romantic relationship. I need some advice. It’s regarding coworkers/ management.

A month ago I applied at a hospital as nutrition ambassador. When I read the duties, it said basically deliver trays to patients/ modify diet plans. I went to school for nutrition and want to start somewhere. Well I got the job.

I was not told the dietary company was contracted and was actually not part of the hospital. I asked if there was room for growth though and they said yes. I also have a schedule restriction. I can’t work Sunday past 1:30. If worked fine because on sundays the nutrition ambassadors work from 5am-1:30.

Today was my first day and let me tell you, I was dying and I wanted to cry so bad. The energy of the ladies there was so bad. They were rude. The girl training me was nice and was already telling me that it’s horrible working there and she’s thinking of quitting when she hits her 6 months. She’s currently living in a hotel so she needs the money. She also told me that I deserve a better position since I went to school. I feel like she was being genuine Bc she straight up told I wouldn’t grow there. So I go deliver trays then I get sent to the kitchen to mop floors and wash dishes. I didn’t know this was part of the deal. A lot of women there were talking in their language and whispering. I am not exaggerating. I felt like a fucking slave. Then I get told I would sundays from 7-4pm. I cannot. The manager left early and I don’t even feel like going tomorrow. I feel like just emailing them politely. I wanted to tell them the environment is not for me and I’m sorry for any inconvenience. I feel so sad. Literally came out crying and feel like it’s a bad start to my job
