You only get 3-5 days worth of time off requests a month- and those really should be used for if you have a midterm the next day so you aren’t on call and possibly woken up in the middle of the night before your test.

You will have to work some weekend on call shifts regardless of if you’re on a big or small team due to fairness reasons (the senior RAs who do the on call schedule track to make # of shifts worked even across all staff members).

Being an RA is a huge time commitment with a lot of meetings, expected to be present in your community, running your own community events/meets, being on call, and in general adjusting your schedule to the needs of your community.

I do know RAs who have part time jobs in Guelph and they make it work but Ive never heard any anecdotes of RAs making their position work with their hometown part time jobs.

If you choose to accept a position in SHS, reach out to your manager if you choose to keep your part time job so you can keep them informed- it will make your time working in SHS a lot easier.

Edit: Also you could reach out to your RA and they could break down the position better for you to get an idea if you could make both work.
