This morning i was off because my shift doesn't start until dinner time. I recieved a phone call from a coworker asking why I was no show this morning for my top up hours. Well because I had never been scheduled for any this morning. Scheduling reached out and I was right, someone put me down without ever contacting me, but there was no one to cover my hours this morning. I work a job where if no one shows, a person will suffer from neglect, so I had no choice but to work even though I had other plans for the morning. This is the second time this has happened to me.
