@Fitterbyfifty, speaking in my function as a Europe-based executive in a global corporation:
The USA are pretty, kindest wording I can think of, fucked up when it comes to sick leave (or any kind of "time off work" for that matter) by European standards.
My US based colleagues have medical leave deducted off their global allowance of "time off".
Thankfully for the rest of us, Global Megacorp Inc. [our employer] doesn't apply that to the rest of us: we get sick leave, bereavement leave, relocation leave, time off in lieu, ... you name it ... in line with local laws.
The US is really not the standard to follow when it comes to employee rights!
