I'm really hoping for some advice!
I'm starting a college course in September (3 days a week), but I do not get the days it'll be on until 22nd August. I do know for certain one of those days will be a Monday, which is great because I don't work Monday. They'll definitely be week days though. And previous years on the course have always done Monday, Thursday and Friday. I work on Thursday, Friday and Saturday....
I absolutely adore my current job and work with people who are doing the profession I'm aiming to do. Everyone is so supportive, funny and lovely. I'm gutted I'm probably going to have to leave.
How do I tell my manager this? I feel so horrible. I only got the job in April. Me leaving would be quite disruptive in terms of staffing.
What would you do/say? Am I being a cheeky fucker leaving so soon after getting the job? I don't want to but I can't be at my current job if I can't go the my college course 
I would be looking at going to Uni in September 2020 so I would've always had to leave soon(ish).
I suppose it would be lovely if my manager kept me on for the Saturday since that'll definitely be the hardest to get someone to work. However, it would've be up to her. We're a charity so the likelihood is it'll be up to Head Office/HR.
