I remember re-covering the roof of an apartment building for a slumlord I worked for in college. We ran out of tar, so I had to wait an hour while the boss went to get some more. Sitting for awhile in the shade of the roof access entrance was glorious. We were supposed to drag our exhausted, aching bodies to the basement to "tidy". We didn't because that was absurd.

Now I sit on my ass all day long and write code. I make enough now that I'm in the class of worker that's allowed to slack and pretend I don't. Sometimes I slack and post to Hacker News in the middle of the day. No union needed!
