In 2003, as part of tort reform measures, Florida passed a horizontal immunity statute.  The statute require a worker on a jobsite working for one subcontractor, to prove gross negligence in actions against other subcontractors who negligently injure such workers on a jobsite.  The gross negligence standard means to knowingly undertake a dangerous act likely to result in injury. 

An article on talks about a recent verdict in a case using this new law.  The plaintiff lost, as the jury was unwilling to say gross negligence applied to the facts.  Another instance of working people suffering the consequences of tort reform and the businesses who paid for tort reform shirking their responsibility for their actions.
