My application was for part time when I was hired because I was working in another place ! after a couple months my manager told me to work full time and she will increase my rate ! I worked there for almost 9 years until I moved to a new area and I requested for transfer and I moved to a new store & they all of the sudden the changed my day shift to tine . after a couple months They fired me for not calling my manager for leaving store and did not lock the door , which My supervisor actually called me to leave and I was never trained for closing and I did not have a key ! Now , I need to get some advice ! what should I do to prove that my manager changed my schedule from part time to full time & most of my paychecks are over 70 hours a week and some I have overtimes between 2 - 5 hrs .
