Sick day law

Interesting how sick days work... employees are permitted 12 sick days a year (without doctor's orders), but they are not single days. They are in groups of four. So, if you are sick one day only, you have used up four days. This results in different behaviors than you see in the US: people do not generally work from home when sick, people tend to only stay home if seriously or highly contagiously sick, people often are out of work for four days when sick (or at least more than one day).
