My boss edits employee time sheets after they have been submitted, and doesn’t let us know that he is changing them. We see that he has done this after we receive our checks, and by then it is to late, even if we really were in the right and him in the wrong. He just says “oh, oops, oh well”. I personally don’t feel that this is okay, but from a real business perspective is this okay?

Yes, he gives you less hours than you really should have gotten. for example… I had to take a 3 hours off last week to take my car into the shop, and said i was going to use my vacation time to cover it, and he said okay. but when i looked at my stub today he didn’t put my time in the way we had already discussed. He said I can’t use just 3 hours vacation I had to use 4, and I said that would have been fine if you had just asked me.

He does this with other employees also.
