That's absolutely correct, and culture change is at the core of this approach. It is pushing culture change down to the level of every single employee.
It can come from anywhere, even from clients. You have dual responsibilities in this. There is the responsibility of the deputy head to provide a safe work environment for employees, but there's also the responsibility of every individual who works in the government to make sure that they comply and that they're part of this culture of prevention.
One of the things we're trying to promote with the new policy in our work with heads of HR and practitioners of anti-harassment is prevention, as opposed to dealing with the situation after the fact.
