Does the Florida Workers’ Comp Law require pre-suit notice in retaliation cases?

Q. We are a private company that provides services under contract to a subdivision of the state. Normally, before any tort lawsuit has been filed against us related to our services to the state agency, we have received a pre-suit notice as required under Section 768.25, Florida Statutes, to trigger a waiver of sovereign immunity. A former employee has brought a lawsuit against us, alleging that his discharge was unlawful workers’ compensation retaliation under Section 440.205, Florida Statutes. However, he never sent us a pre-suit notice for this statutory tort. Can we get the case thrown out?
