I am an office clerk in the trucking industry and my scheduled shift is 3:00pm to 11:00pm M-F. However, this week they have had me coming into work at 1:30pm and 1:00pm. I am expected to stay at work until everything is done for the night. This entire week, I have not left until around 1:15am. I left at midnight on Monday and my manager was upset and said that he really needed the help. The job is very understaffed, so my manager genuinely needed the help as he often is doing everyone’s job at once. When I leave, he has to finish my job. I honestly feel like that’s not my problem and this is not going to work if I keep having to work past my shift. Thoughts?
