It doesn't work like that. If I took more than two periods of sick a year I'd be sackable in theory. It wouldn't matter if the three periods were only one day each. I've had one day off sick already this year.
RTC, do you change out those 500 songs once a week? Every few weeks? Once a month? I've always wondered about people who use their phones or iPod nanos (or something comparable without much space) as music players. I've got a 160 GB iPod that has all of my music on it, and I couldn't imagine it any other way.
