Actually Jonkster I’d use consultants for the task of changing the culture because they can do the job and go away. The trouble with hiring an internal unit to do this is “Parkinson’s Law” - work expands to fill the time available for its completion. This is not just an anecdote. What this means for the poor airservices staff is that they will NEVER be free of gender wars, inclusiveness, harassment programs for the rest of their employment. These new hires will have tremendous power because even the mere allegation of impropriety these days is enough to destroy anyone’s career. They will use that power to “burrow in” to the center of the organisation and can never be removed.
I am not a fan of bullying and sexual harassment - I’ve been a victim myself. I hope Airservices can change their culture, however I don’t believe a fully funded internal unit is the way to go. There are plenty of consultants who can do the job cheaper and better.
