Cover-ups or just plain old erasing

Sundays, we have a bare minimum staff of librarians. Because of this, the floor manager and the supervisors rotate Sundays. This past Sunday, the scheduled supervisor did a no show, no call. My co-worker whom we can never depend on to show up, was there and trying her best to find excuses for the supervisor's behavior. I told her to chalk it up and we'd just have extra hours on the reference desk.

This wasn't going to work for her, because she didn't want to do any extra hours. Although, on the days when she decides to call in "sick," that is what we do. We work around the missing person. So, she called the person who was in charge of the whole building and informed him. He tried to call the supervisor. He told us that she had given the wrong number as her home contact number.

Monday arrives and I discovered that the official desk schedule hadn't been changed to reflect how we actually covered the two reference desks. My co-worker(librarian who looks like me) told me that I should change the original. I went in search of the altered copy, and it was no where to be found. The supervisor in question had entered the staff area from the direction of where the copy was filed. Instead of accusing, I simply made the changes from memory. As I'm doing this, the supervisor with the floor manager in tow, walks over to where I was, and said, "I forgot to come to work yesterday." I said, "WE KNOW!" I walked away. She then says in frustration, "I guess that I'll work today, and I'll take two of Nexgrl's hours. Is that okay." My response was, "Yea, okay." In addition to this, she changed Tuesdays schedule, so that I would only have one hour on the desk.
