<human>: So, here goes. At the software development company where I work I have 3 colleagues. Two of them, including myself are salaried and are required to work at least 41 hours. The 3rd is our graphic designer who is paid hourly. The problem lies with the hourly employee, as I believe that he is lying about his hours to inflate his income. I've been suspecting for a while based on a few odd things. First, he prefers to work hours where no one else is in the office. This means that he will come in late and stay "working" until late in the evening. This would be fine, but it seems a little odd. Also, he prefers to come in on weekends to work as well. Again, a little odd, but nothing too worry some. Next, I've been noticing that when he is here, he takes really long lunch/bathroom breaks. I usually take a later lunch than my other colleagues, (the two other salaried employees), but I noticed that when they go to lunch, the hourly employee goes to the bathroom or takes some sort of break, (usually for 1-1.5 hours). I'm pretty sure this is on the clock, then he takes lunch after I leave, (I've come back early and found him out to lunch). Again this is starting to seem shady but not completely outrageous. The final straw happened the other day when my manager was out. The hourly employee decided to take a break and when I walked outside to have a cig, I saw him sleeping in his car WHILE clocked in. This whole issue wouldn't be a terribly issue if it wasn't for the fact that his work performance is slowing our entire project down. If he has really been working, he should have a lot more to show for the hours he's put in. Now its starting to effect me, as I'm waiting for his designs, and I've decided I need to catch this guy in the act, I just can't figure out how. Any advice would be appreciated, but I cannot access his computer, (work privacy issues), or do anything that would violate his privacy rights. Also, we don't have any cameras at my office.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Coworker is milking hours and slowing down progress due to lack of work. Need to catch him in the act without violating his privacy.
