I think that's a good idea, but really, policies are only as effective as the people who enforce them. If you have a workplace adviser, that's wonderful. But if he or she goes to the next chain of command, and that person thinks these are just silly little complaints, then nothing will be resolved. Eventually that just becomes a toxic workplace.
The entire RCMP organization and federal government employees have to buy into this idea that having a harassment-free, bully-free workplace is in the best interests of everybody for the emotional and financial parts of an organization.
Think about it. People are on sick leave for five years. If they're getting paid $90,000, that's a lot of money. I think they would rather be working in a healthy workplace than sitting at home and stressing.
