It would appear that it is either a zealous management type trying to earn brownie points or, as has been suggested, a shot across the bows to signal the commencement of a new, hard line industrial policy from management.
Or, these pilots have lied about their address and are commiting a crime, for which they rightly should be punished!
I am concerened that people are more wortied that the media know about this than they are that the alleged crime took place.
