Does anybody withdraw from on-campus jobs?

Hello, I am working an on-campus job but I got the offer from a full-time job with great money,

I will be graduating soon but my on-campus job contract is until this june,

Would it be ok to withdraw from this on-campus job with no legal issue or anything like that?
