I have found people sleeping on the job, and have slept on the clock myself.
One day I was talking to a coworker over a cubicle wall. He wasn't responding so I figured he had his headphones on. I walked around the cubicle and found him sitting upright in his chair, sound asleep. I went back to my desk and let him sleep.
I came into work a couple hours early one day (5:00a.m.) to pick up some overtime as we were very busy. A storm earlier in the morning had knocked out the power to part of town, including the building I work in. No power, no lights, no computer, no other people in the building and nothing I could do but wait until it came back on. So I laid down on the floor in my cubicle and went to sleep until the power came back on. I got paid time and a half to take a nap.
