Based on the context and the answer, generate a question. 

Context: Well , I actually finally found a job , so now I work 10 hours a week for just above minimum wage . They would be happy to give me more hours , but the student union prevents me from working more than 10 hours per week , and my job is on campus so this is tracked . I still , of course , have to pay full tuition , which amounts to $ 500 a month , or $ 100 a month more than I am allowed to earn . Not to mention rent , food , gas , clothes , books ... I really do n't understand academia .

Answer:

The student union has rules in place for campus jobs .



What may be the reason for their lack of hours ?
