I've been on med leave a million times. As a matter of fact I just came back to work from being off for 2 1/2 months. I am also on intermittent FMLA every year so when I have bad days and can't function. I don't know how each company is or the laws are across the board but I am allowed 480 hours of intermittent FMLA in a rolling 12 month period. Without having this I would have lost my job a long time ago. You have to realize that mental illness is considered an illness just like any physical illness. This is what HR told me when I first had to deal with this stuff. It would be discrimination if you were denied because it is a disability.
