"the employees in question had demonstrated violent behavior against management and clients." If true, then action should be taken against those who allegedly guilty of this behavior. I find it hard to believe that 21 employees were involved in the same incident. If clients were involved, then the company should have no problem proving its case IN A COURT OF LAW and file criminal charges. Let's see the evidence and have the judges make the final decision!
