I just got hired in a new retail job on the 6th, with the schedule of Monday to Thursday. On Thursday, the store manager told me that they need me to work from Sunday to Wednesday instead. I wasn't happy about working on Sunday, but I agreed with it.
I went to work on Sunday. Then today, on Monday, I unfortunately had some bad food poisoning and I felt like I wouldn't be able to do my job, so I notified my manager in the morning that I would be absent and explained the situation.
He demanded that I then work on Friday as a “make up” day. I refused, stating that the schedule we agreed to was Sunday to Wednesday. He said that I changed the schedule, not him, and he's “not thrilled” with my response. He wants to talk about it in the morning tomorrow.
I've never heard of working a “make up” day. This isn't school or an office job with a project deadline, it's a retail job. I plan to stick to my conviction and refuse working any make up days, fully expecting to get fired in the morning. But am I just being a stubborn idiot or is the manager unreasonable?
