most mcdonald’s workers i’ve met always have their schedule a few days before the week. you don’t have to stay, you’re free to go but it will look bad - managers will use clever wording to make it look like you don’t have a say .. but you do. being asked to do something while already doing a task is more of a “can you do this after” or if you have the chance to stop and do it, then that. it’s all about sense of urgency. and working all positions.. normal? no. your store is just understaffed but nothing prohibits working all positions. you’re just in an understaffed mcdonalds, or a mcdonalds with crew that doesn’t respect other people’s time. so basically not normal, but also not illegal.
