This is a dumb question, but with all the computer/cellphone/handheld games being used after work hours, how do you know that your CPS is due to work? (I work a desk job, so I'm on the computer ALL the time.)
I'm just curious - I'm not at all implying that you don't deserve the compensation (or that you didn't get it at work)...
In my case it was easy, it started in the early '90's before computers/cellphones/etc. were common. I was a casino dealer and didn't have any problems until I picked up black jack. The casinos knew the repetitive movements involved in dealing black jack were an issue, but didn't want to either change the movements or admit there was a problem. Maybe things have changed now, I had to quit after 3 surgeries in 2 years.
