Mick Cash
Unusually for a general secretary he is in the thick of this dispute and “hands on.”
He took over from Crow – but you will never see him in public in casual clothes or wearing a baseball cap.
Mr Cash, always immaculate in suit and tie, has been described as the iron fist in the velvet glove. He is equally determined, albeit with a different approach, as his predecessor to fight for his members.
He stands somewhat apart in RMT hierarchy by being a member of the Labour Party – which the union is not affiliated to following a row.
Mr Cash commands one of the few unions both to retain real industrial muscle, which it is not frightened to use, and a rising membership – 80,000 plus.
Paul Cox
He is little known outside the rail industry but has, in union terms, become a key figure within the Southern dispute.
The bearded RMT regional organiser has been the most frequent face on television and voice on radio as a spokesman for the increasingly bitter dispute.
Frequently seen at Brighton Station and on the picket line he is softly spoken but retains an in-depth knowledge of the subject and is never flummoxed by any question.
He was one of the first to tangle with Southern when the company complained of high levels of apparently “organised” sick leave among staff – an accusation he “emphatically and categorically denied.”
Steve Hedley
An assistant general secretary in charge of the London Region he is more usually associated with strikes on the Tube.
Never one to be left out of an industrial dispute he has been vocal about Southern. He makes clear: “Our members are not prepared to sit back and allow the guards to be taken off the train... the guards are there if a driver takes sick, if there’s a fire on the train, if there’s a terrorist attack.”
Once tipped as a successor to Bob Crow, Mr Hedley is one of the more vocal union members. He was banned from LBC radio following a heated clash with host Nick Ferrari who said he was “vile and abusive” and that he never wanted him on his programme again.
