There was a guy I knew of at Earthlink (ISP) (where I worked once) that missed most days yet kept his job. He used every excuse he could and somehow kept the job. He only showed up for the last month or so to qualify for the extra money you would get when Earthlink announced they were moving the call center overseas along with Earthlink paying for school.
I imagine he next got a job with the state gov’t and is looking at a fat pension while still not doing any work.
I worked a contract where one of the govies had cut up a cardboard box and taped the pieces to the top of his cube so that the lights wouldn’t disturb his sleep. Unfortunately he was the one responsible for some of my team’s systems, and whenever we needed to push a patch to production, I had to go over and wake him up to get his approval.
