For all FMLA (including PPL now), intermittent leave is subject to your supervisor's approval.Right when you decide to come back, the rest is dependent upon staffing
I know there's ATMs out there that say "once you're back, you're back permanently."
That is not true (except for the people that tried to just use FMLA on just their 5/5 or 5/10 work days...that clearly is cheating and circumventing.)
There's an HRPM that talks all about it. Which apparently some in management have had trouble applying correctly.
