Some interesting points which I generally disagree with, but that will be of no shock to you.
I would suggest that the insurance policy, however poor, would be better than none. In my company we have union and non unionised groups. Which do you think have the greater influence?
Still, if you like to include terms like trots and pinko's in your point, then I doubt if you would reach out to the non engaged. Still, I am sure it serves a purpose somewhere.
