Background: My coworkers and I are Circulation Assistants in our university's library. If we need time off we write it on the board, someone writes if they can cover the whole shift or part of it, and one of our supervisors initials it. If there is an emergency, we can text/call our coworkers to find someone to cover the shift, and the person covering will write the information on the board when they clock in. The schedule is put out three weeks in advance and rarely changes. Also, the library closes at 6pm on Saturday, we have to have 2 people to close, and there are only 2 people scheduled to work at a time.
Coworker A is scheduled to work 2-6pm every other Saturday. Yesterday evening, she sent out a mass text message to everybody asking if someone could take the shift because she needed to go to Nearby City, about an hours drive from campus. A few seconds later, she replied that she found someone to cover it. A few hours later, she sent out ANOTHER mass text message asking if someone could just take the 2-4pm shift. Since her original text message implied that she was having an emergency, I volunteered for it. We then had a short exchange detailing if she would take 2 of my hours on Sunday as we are required to exchange hours to avoid going into overtime.*
Well, when I got to work today, there was a message on the board saying Coworker Q would be taking the 4-6pm shift. All is well until about 3:55pm. Q usually shows up about 10 minutes before he starts his shift so I start getting anxious. By 4:30 I was livid and was planning on having a long conversation with Boss C Monday morning, but ended up messaging her instead. She immediately called the library, and told me that A had been pawning off her Saturday shift whenever she had it, and apparently when Q told A that he wouldn't be able to come in, she went anyway! At that point A should have taken the shift herself instead of going out of town, which incidentally was visit with her niece, not for any emergency.
Then Boss C tells me that she is going to have a LONG talk with A Monday, and asks if I could finish the shift, and perhaps be interested in taking A's Saturday shifts in the future? I agreed and she got off the phone after saying something about having a glass of wine(totally understandable in my opinion). Now, this is not a hard job. We can surf the web and go on any university allowed site including Facebook and Netflix while on the clock as long as we help customers when they come to the desk. Once an hour we have to go fill the printers, check the book drops, push in chairs, and put up books. Our bosses let us take paid breaks to eat meals and often bring in snacks, drinks, and other goodies to show they appreciate us. This is one of the cushiest jobs on campus, and A is probably going to lose it because she can't be bothered to let someone know that either 1) She can't/won't work Saturdays and 2) She didn't tell anyone that no one would be available to work for a 2 hour closing shift, leaving someone to try and get everyone to leave the building and clean up by herself.
It's a good thing A is graduating in May because after this, and previous incidents, I don't think she would be asked to stay on during the summer if this incident didn't lead to her termination.
* She told me she would work the hours if I needed her to, but she doesn't care about getting her hours back. Since she works 2pm-8pm Sunday, and I work 8pm-12am, I highly doubt she would bother if I needed her to.
