Does anyone else think the world would be a better place if there was a law brought in that 2 days a year, you're allowed to call in ... not 'sick', but just 'I've got better shit to do than come to work'?
So many people do it, for sports events, big game or movie releases, hell, I've heard of people taking days off to get the new Harry Potter book, so, instead of just lying and phoning work with your 'sick' voice, which you seeming have to put on even if you say you've done your back in, just make everyone honest and say, can't come in today, I want to play games all day.
The world is more honest, staff are happier, and nothing else really changes, as they were gonna skip work anyways.
