We have an old guy, and I mean old, 71, who has called in 3 times in last 3 weeks, once a week. He doesn't look any worse when he comes back the next day and since he's off Monday's he's getting a 4 day weekend each week. There's just the three of us plus guy who brings freight so we end up running. We suspect he's about to retire and having a little fun at company's expense. This is a new one for me, had never considered taking my unused sick days before I quit.
