Non - Continuous employment FMLA qualifications?

The FMLA is not the easiest law to work with for either employers or employees, thus, I'd recommend you turn to the experts and call your local US DOL office and talk with the officer of the day. While it appears that you qualify, there may be a limit to how long ago your previous work with the company may be before being irrelevant. The FMLA is full of loopholes like that.
