"Of course the best way to reduce costs and improve efficiency is to remove as many layers of managers as possible - which is easily doable if you put people with technical competence in the senior management positions. "
Yep! A PROVEN formula!
That is precisely what happened to the ole' Flight Service' heirarchy in its 'downsizing' days....
The middle managers were made redundant, got the 'golden handshake', OR RETURNED TO 'THE FLOOR' - read console - and actual day to day management passed on to the 'on the floor' working staff, who actually managed - and reported to ONE manager above!!
THAT LIST IS "A M A Z I N G ".............
