I'd just add that like all government departments we have a grievance process in place, with first, second, and third levels. It's rare that we don't solve these issues at the third level--in other words, they don't go to arbitration, they don't go to the Human Rights Commission, etc.
What we try to do, though, when we get complaints or allegations, such as harassment, for example, is to resolve them through internal conflict resolution. We have a very effective program in place in the department. We try to work with the employees who are represented by the unions through negotiation and consultation as much as possible, as opposed to going through the formal grievance process. But occasionally we're required to go through those steps.
