Do I have to work this? Please read info.
Okay, I'm a guard for a company who makes Semi-truck transmissions. We have a total of 6 people who work here. There are three shifts, I work overnights, Monday thru Friday. I got to work tonight, my boss changed my schedule and is having me work a Saturday for one of our weekend guys, because he has plans. Well I have family coming from out of town that weekend. Do I have to work that shift? Or can I refuse? I'm afraid of getting fired.
