New employee here, am I allowed to ask that I'm not scheduled at certain times?
I'm 16m, just got hired as a seasonal part-time worker from now until January 31st at my local Dollarama. I just worked my first shift yesterday, and I signed myself up for ~8-10 hours per week, available Fridays after school and weekends all day on my application. This is my very first job, so I really don't at all know how I'm supposed to go about this.
Just to be clear, this isn't about changing my schedule, the schedule comes out weekly, and these weeks have not been scheduled yet. I just want to know if I can request not be scheduled on specific hours of specific days.
Firstly, I'm worried I'm going to be scheduled Halloween night. My manager said I'm probably going to be working evening shifts next week, and I'm afraid that's going to become a continuing trend the next week. Would it be okay if I sent her a message asking that I'm not scheduled on an evening shift that day/weekend? Something along the lines of "I'm wondering if it would be possible to request I'm not scheduled on an evening shift on the 31st".
Secondly, I'm part of my school play, and there are a few Saturdays in the year where we have to go in and work on the play. If I know I have to go in on a Saturday, is it okay for me to ask my boss not to schedule me for the hours I have to be at school? Should I just send my manager a message that says I am unavailable at those hours?
