I'm in college and my summer job is working in an office. It's a perfect set up because during the school year I take a computer with me to school and work from home according to my own schedule. But for these three months during the summer in expected to be in the office working. Not unreasonable, but what's killing me is sitting all day! My back is in so much pain despite me getting up every hour and walking the halls for 5 minutes. I also get an hour lunch but sometimes I work through it for an extra hour's pay. 

Does anyone else sit at a desk all day and has had experience with this?? Anything else I can be doing or do I just have to "suck it up"??
