This guy I work with, on top of being totally disorganized and not good at his job, is also chronically late. We were told before he was hired on that he had a tardiness problem but we were short staffed and I suppose we underestimated the issue. The guy comes in at least 30 mn late every single day. This has been going on for a couple of years and we have found out that it is due to a medical condition for which he's being treated. While I don't know the exact diagnosis, the only one I can come up with is delayed sleep phase disorder, where a person biological clock is off and they can't fall asleep until very late and have a very hard time waking up in the morning. He was so late a couple of times last week that he simply took those mornings off and didn't show up until after lunch. Here is the kicker though. When the guy was scheduled to start his job at 8:30, he would show up around 9:00 or later, thus demonstrating that he CAN make ~9:00 work, but now that his start time has been changed to 9:00, He never comes in until at least 9:30. This doesn't compute at all. Anyone ever heard of something similar? I smell bullpoop.
