Okay so I have two jobs in different hospitals. Their both per diems (no benefits)

One of the jobs I just got in December which I wanna leave so badly. 4am to 230 pm it’s so demanding that I can’t sometimes take my lunch or break without falling behind. Nurses and staffing are unprofessional. It’s in the middle of downtown. I hate driving so early in the mornings around there because of homeless. And sometimes I see them in our parking structure. I know it’s only been 2 months but I’ve never been so fed up with a work place. I wanna tell my manager thank you for the opportunity but it isn’t for me before my 3 month probation is over. Because otherwise starting next week the coordinator is going to start to depend on me to cover people schedule. My other job that I’ve been at for 3 years has a full time position opening soon. And I don’t wanna leave once she’s going to depend on me( I think it’ll be messed up and unprofessional if I mess up everyone’s schedule knowingly that I was going to leave)

So the plan is let my manager know it isn’t for me this week or next Monday and just wait for the full time position to open at my other job since I’m next in line to get it. Which I am still also working.

I just don’t know if I’m doing the right thing. This job I’m leaving everybody wants to get in it and is very competitive and there’s other people that just hate the hospital cause they work u to the bone.

I super dread going to work there like on my days off my stomach turns just thinking about it

Am I doing the right thing to let it go?
