You get 12 workweeks of FMLA leave. But as you may know, 12 workweeks of time off leaves plenty of room for interpretation as to exactly how much time you get off. This is especially true when you have already taken some time off in the year.
The general rule is that you are charged leave for your actual usage, according to the Department of Labor. So if you take leave for one full workweek, you will be charged one workweek.
On the other hand, if you take intermittent leave or only need two days off in the week, you should only be charged for that proportion of that workweek for which you take time off. For example, if you only take one day off in a five-day workweek, you should be charged one-fifth of a workweek only.
