—in any context. I don't believe it's confined to the public sector. It's a very difficult thing. The research paper we published at the end of 2016, “The Sound of Silence”, highlighted the two major fears. The first is a fear of reprisal and the second is—I don't know if you'd call it a fear—a concern that “nothing is going to be done anyway, so why should I bother?”, given the risks involved.
My views are that it is very difficult, that it takes more than an office of 35 people to change the culture of a 400,000-member public service and that it requires efforts at all levels in all organizations at all times.
