I was told by my boss that I cannot work overtime, but then I got stuck there answering phones and taking care of a customer. So I did not get to clock out until 5:50. My shift ends at 5:30. So since I was there 20 minutes over I was told that I have to leave 20 minutes early the next day, and not get overtime pay for that time.
I work for a retail mail order company.
Can an employer do this and not pay you for the time?
