Oh, as a heads up for @missbunnyrabbit, if retail is so easy you’ll be able to walk into a seasonal job starting soon and then go from there. Might as well pack in teaching and just go stack some shelves for 42.5h a week. And as an example rota, how does this suit you?
Monday- 6am-3pm
Tuesday- 3pm-12am
Wednesday- 6am-3pm
Thursday- off
Friday- 9am-6pm
Saturday- 3pm-12pm
Sunday- 6am-3pm
Two days off together? No chance!
Working back to backs? Yep. Oh, and they’ll request you sign a waiver so you can work on that little sleep. You don’t have to sign it, but you’ll not last long, probably. So you’ll sign it and get used to working on 4 hours sleep pretty soon.
Oh, and you think those 3pm-12am shifts are okay at first. You can have a lie in. Until you realise that you can’t do a single thing on those days other than work. Can’t get up too early or you’ll crash and burn by 8pm. Get up any later, and there’s no point doing anything. And you’ll likely have an earlier shift the next day so you’ll have to keep that in mind, too.
Oh, and what about the Christmas rota? You’ll likely work Christmas Eve morning or evening. Hopefully off Christmas Day (maybe not, though). Can’t drink because you’ll be back in for Boxing Day sales. Same story for New Years- you might be off one or the other but it’ll make it impossible for you to make plans.
