So when I first started working here they were scheduling me about 15-17 hours per week which was fine and gave me a good, full schedule with time to rest between studying, classes and work. Now I’m working closer to 25 hours a week, including working from open to noon, (about 8 hours) on my busiest day of the week. I feel completely exhausted, and I feel like my boundaries aren’t being respected. For additional context, my requests for time off on specific dates aren’t being approved (things like my birthday, father’s wedding) and I’m left responsible to delegate the hours that they scheduled me for on days I specifically said I couldn’t work. I just need them to back off. How do I let my employers know I want to work less hours?
