I have a whistleblower action agasint the County of Los Angeles. What is the statute of limitation?
Generally 1 year from the event, but for federal EEOC claims 180 days, and same for claims against the government to fulfill the requirement to exhaust administrative claims, and once you file the claim with the DFEH or EEOC, the statute is tolled while they investigate and before they issue a "right to sue" letter (but you can request a letter without an investigation if you know you're going to sue).
Don't wait, see an employment lawyer ASAP to preserve your rights.
