Morning Class Clash

You work part-time at a café and usually start at eight. Your new timetable has a compulsory nine o'clock lecture on Tuesdays, so you cannot do the opening shift that day. Speak to your manager before your shift: explain the clash, offer to work a different day or a later start, and ask whether that works.

Hi, could I grab you for a minute before we open? My new semester timetable just came out, and unfortunately I've got a compulsory lecture at nine every Tuesday with attendance marked. That means I can't do the eight o'clock opening shift on Tuesdays anymore. I'm really keen to keep my hours, though, so I could start at eleven on Tuesdays instead, or take the Thursday morning shift if that's still open. Would either of those work for the roster? Thanks for being flexible, I really appreciate it.
