What can I do if my employer won't give me hours?

I've been workin for this company for about 8 months. There are several departments at this company to transfer to. The season changed which means the department i was working at closed. I have asked to be transferred to another department took the appropriate actions to get my transfer started and my boss will not turn my papers in. I've asked her numerous times what is happening and she says she is looking into it. she says I'm not fired she just doesn't have any hrs to give to me. What can i do about being employed but not recieving any hours?
