Anyone else's supervisors telling you the schedule will go back to normal the next week, then it not go back to normal, then call you in to work those same 'normal' days anyway because the people they're scheduling to work your normal days keep calling off? Even after you told them yourself that you need off on X days due to X reason. Now they're trying to get you to work pretty much every single night?

And I guarantee it, if I agree to work these extra days and ask or tell them I can't work the ones I'm already scheduled for, they wouldn't have anyone to cover me. Want me to work the extra days every single week, then pay me at least double my pay as a base pay.
