[R0b0t1]

From random reading on the DOL website I am pretty sure she should not have been fired. However, some of her pay could have been withheld (possibly contingent on her being classified as hourly or piecewise paid). The previously tested scenario was dialysis.

So as I understand it, if you have e.g. end stage kidney disease, you don't need to inform your employer of the fact you must be gone two times a week for three hours, and they can not fire you when they find out. But they also don't have to pay you.

However the rules about salaried positions seem to imply they can't reduce your salary.
