Girlfriends job and homework getting in way of hanging out

My girlfriend recently got a part time job but it's cutting into our hanging out time. She only works 2-3 week-days a week but on the days we work we can hang out for an hour max. The problem is she doesn't have time to do homework on the days she works so the whole afternoon she doesn't work, she's doing homework. It's not fair to me in our relationship that this is happening. I don't want to say you have to choose me or your job, but it feel like that's the only option. Any suggestions?
