In the aftermath, several workers filed a lawsuit claiming they were told they couldn't leave the factory in the hours leading up to the tornado.Today, Amos Jones, the same attorney who filed the original lawsuit, filed an NLRB complaint on behalf of 20 employees."That's when we saw a lot of kick-off of persons who were not represented yet, directly, by us and so people came forward to allege that they believe that, because of the fines and their having spoken up, in violation of what two persons just yesterday reported were warnings in the hours after the tornado, written warnings, electronically, at least, from Mayfield Consumer Products, advising them no, do not speak to the OSHA investigators," Jones said.He said some of the workers are being called by bill collectors for payment of medical bills from the tornado that the company's insurance hasn't paid.We're still calculating numbers, as people come in and we do our best to get hold of records, but it's a significant sum of money already in collections for these victims, who have post-traumatic stress disorder and other horrible maladies," Jones said."
