This happened in Oct - Nov 2010.
WAY too late to allege wrongful termination now.
Not so. Wrongful termination claims based on illegal discrimination under federal law (i.e. based on race, sex, religion, national origin, age, disability, or genetic test information) must generally be filed with the EEOC within 180 days, though that can be as long as 300 days in states that have agencies to investigate such claims.
This is not, however, one of those illegal discrimination claims, and no claim must be filed with the EEOC at all. Indeed, the EEOC is not the agency that enforces the FMLA, it is the DOL Wage and Hour Division. The FMLA provides a statute of limitation of TWO YEARS to file the civil action. 29 U.S.C. § 2617(c).
I suggest the OP consult a civil litigation attorney ASAP to see how strong a case he may have and what damages he may be entitled to receive.
