So I work at a Starbucks on weekends because of school and my extracurriculars (I'm 17 and a senior for reference). A little over a month ago I requested time off for GradBash because I'd be returning from Orlando around 6am on the 2nd of April and would have had an 8 hour shift later on that day. For over a month my school has stated that GradBash would be on the 1st & 2nd and I made the time off request and had it approved last month, it is currently spring break but the event organizer sent out an email today saying that due to an issue between the bus company and the school GradBash is being rescheduled from the 1st & 2nd to the 8th & 9th. Now I can't get my schedule changed (because it's made 3 weeks in advance) so that I can get back the day I would have had work and I have to work on the 9th because there's no one to cover my shift.
