I have been. I was in school and I was sharing a car, so when I went to the gas station for my interview and was told I would be working 2 - 10 every Saturday I was psyched. Exactly what I needed.
But not so much. I was under the impression that I had a set schedule. The schedules came out on Mondays and it was kinda far from my house, so I never checked it. This became a problem quite quickly when management kept scheduling me for different hours - usually more hours. So when I showed up on Saturday at 2 and the people were pissed because I was supposed to be there at noon, I told them I was told when I was hired, that I was working 2 - 10.
This did not make me popular. Actually everyone hated me and this continued for a few months. Finally I found a different job at a restaurant and I put in my two week notice. I was moving the Saturday after I put in my notice and had requested the day off. Again, I didn't check my schedule and didn't know I wasn't given the day off. I mean, I would've taken the day off either way because I was moving - what did they want me to do?
So, while I was moving, I got a phone call telling me I was fired. But how could I be fired after I had quit??
