As a retired employee of ATT I observed instances firsthand of FMLA abuse. All it takes is a willing doctor. If invoked properly there isn't much an employer can do. Document, document, document...
There are even books(user manuals) on how to maximize FLMA. It lowered workplace morale when we saw people getting time off with pay for no good reason and management could/would do nothing to change it. Good luck!

You know that FMLA is unpaid leave right.
