We all get sick, and sometimes we need to take time off from work to recover. With that being said, how much notice do you have to give to your boss when you decide to call in sick? Should you call the day you're scheduled to work? Or should you try to call at least a day or more before? Of course you can't always predict when sickness will hit, but I think giving a few days notice is ideal, unless it's something that hits you all at once. What about you?
