Our employees have a number of protections. They have an internal ombudsman. They have external.... They can go to the TSB. They can work through the union. There are lots of ways to handle it if a company were ever to go over and above what they need to do to correct behaviour for the employees. That's not our philosophy. Our philosophy is to change people's behaviour using the minimum amount of discipline, and it's important for us to stay there.
