That is outlined in the policy. Different departments will handle that in different ways, depending on their operational environment. There is no shortage of information available to employees, though, in terms of guides and the policy and so on.
For instance, when Treasury Board approved this new policy, emails and communications were sent out to deputy heads and heads of human resources. These were sent throughout departments and organizations around the federal government. I think no one should be able to claim that they didn't know this. Those materials are amply available.
I'll just add that the School of Public Service offers multiple courses on prevention of harassment, so there's no shortage of tools available for people if they want to use them.
