Over at Kotaku, Mark has posted a guide to chucking the perfect sickie for people who want to play Portal 2 (or any other major new game release). While it's very tongue in cheek (and arguably not needed when many of us are looking forward to a five-day weekend), it does raise some useful points worth remembering if you plan to take a day off work that isn't entirely due to sickness.
Amongst the familiar reminders (avoid scheduling a sick day next to a weekend, don't reveal what you're up to via Facebook), Mark notes that "pre-scheduling" your sick day may be more convincing:
If possible, set up your sickie in advance. Display subtle symptoms on the day before if possible – sniffles, sneezes if you’re going to play the flu/cold card. Stomach pains and subtle moans if you’re pulling the gastro sickie. Making your boss or supervisor say, ‘why are you in the office you crazy, overworked son of a bitch?’ is your goal here. You are playing the role of the loyal worker bee, sacrificing the needs of his own health for the sake of the colony.
Which tactics have you used to score time off in the past? Are you sick of co-workers not taking their share of the load? Tell us in the comments.
