Asking because my boss has repeatedly assigned me shifts within a nine-hour window without a text or call regarding the change. I wake up to a notification from our work app telling me, “A shift you have starts in an hour.” Or even worse, “you have missed clocking in for your shift,” when she decides my work day starts at 6 am. I'm getting really frustrated with her lack of scheduling ability and how difficult it is to have a life when my day could change at any minute. I know I'm not the only one affected by her lack of planning, and I am aware that she is a new business owner, but I feel like a 24-hour notice is not an unreasonable request. I've tried looking up laws about this in Montana, but I can't find anything that eludes to rules or requirements regarding scheduling here.
