You are probably out of luck on this one - but if you are traveling out of state maybe you could come up with a different claim. Do you get paid overtime? What state are you in?
...of state and share a room? I have a bad back but my employer forced me to sleep on the hotel floor for 5 days. Ha wanted to cut back on costs so he shared a room with another vendor but I had to get the floor. I only slept about 3 hours a night and woke up with back pain each day. I could go on with so much more stuff this employer does but this is the real question.
