I'm going to get called in on my second day off and ignore it
Why do you think they will call you?
I have been called in every time I've been on a leave from work
Those are your days off. You shouldn't have to go in on your days off.
It's the manager's fault for calling me in, I don't want to deal with this shit.
What they are doing to you is rude. You only need to work the hours on the schedule, you can file a complaint with the labor bureau for harassment if it gets bad.
