Thank you everyone for the advice!!
I already have a job that I've worked at for a year, and from Monday I'm working full time. I'm also taking a year out to save up money by working until about March 2024, then travelling until September (I have a deferred uni placement). And I think I will look for a job then, and from the sounds of it larger chains seem to be better with hours?
Currently I work in smaller business hospitality and there is a pressure of when I'm given more hours than I ask for and I'd rather not deal with that pressure at Uni. Thank you so much!!
