I am an ex-Channex employee and I sadly have to concur with most of the negative comments here. PM can be an extremely difficult boss and definitely goes by the 'Joseph Stalin' school of subordinate handling. He can in an instant turn from the most charming man into the world to being threatening and abusive and then back to being charming in almost the same breath. You just need to think of a number of such people you have heard of - Donald Trump, Robert Maxwell, Alan Sugar, Michael O'Leary, Rupert Murdoch etc - they all have similar qualities. PM has sacked a number of his employees on the spot in the past. The sad truth is that these are the qualities which bring people to the top of our society but they are also the ones that bring them down. There is no dealing with these guys - you either take them as they are or you leave.
My abiding memory of him will be 'early morning prayers' where all employees at the Bournemouth office had to turn up for the morning briefing given by the Ops Officers and supervised by PM himelf. Often after a night of freight operations in the middle of a UK winter they would have a number of difficult situations to handle like aircraft diverting all round the country due fog etc. After the briefing by the Ops guys, they would then be subjected to public abuse by PM in front of all the secrataries, suppliers, engineers etc and told how terrible their decisions were etc. It was a truly dreadful and demeaning sight and absolutely repulsed me (and virtually everyone else watching).
Incidentally, Channex has the worst safety record of any airline in Britain by a long way. In my time there they had 3 accidents including one fatal one that killed both pilots in an F27 crash. I was much earlier on in my commercial flying career then, but I came closer there to my demise than at any time during my previous RAF career and my subsequent commercial career. It would be hard to blame PM directly for all that - fundamentally it was a cultural problem created indirectly by him and which was extremely difficult to tackle. I do not criticise anyone for working there - circumstances in our lives are such that it is sometimes necessary to work places we would rather not be. I wish all the guys at Jet2 the best - it is without doubt the rock bottom end of the jet market and the second they get a chance to leave they should do so.
