Control
This is really just about control.
Why chat with the accused few when you can intimidate the majority of 'sheep' with a NTC that could give future grounds to discipline/dismiss individuals for not complying with company policy.
The 'management' live by the belief that that they are solely employed to protect the reputation of this company from the crew they sadly attempt to manage by constantly monitoring everything we do in the hope they find something they don't like. If they had any people skills at all, NTC's would only contain operationally relevant information disseminated to improve what we do and not used as group reminders to take a **** before getting dressed to come to work.
With a few notable exceptions, these individuals are not qualified to manage anything but are just products of the CX 'old boy network' of internal advancement and the job justification programme. The eternal challenge, to re-invent the perfectly serviceable wheel at every opportunity and as a result climb the corporate ladder at others expense.
Whether you agree with the sentiment of the NTC or not, individual offenders should be counselled in private. The policy of shooting everyone in the room does nothing more than advance the dislike of management and continue to erode what little morale we have left amongst the majority of our crews.
HC doesn't really care about your hat or my tie, he just wants everybody to know that he is watching and therefore continues to propagate the fantasy that he is in control of your destiny in a sad attempt to keep you on the company line.
Wonder who's more gullible?
