I've seen plenty of occasions where the union staffers within a company will do whatever it takes to remain 'off the road', at whatever cost. If that meant cosying up to the management and supporting them over the drivers, then that's what they did. If that meant stiffing the drivers over a pay deal ("go on lads, chucking in your sick pay in return for a 20p p/h increase is good value!") then they would, just to remain 'in power'.
Unions are nothing more than a legalised pyramid scheme, designed to give the people at the top (Bob Crow - £141k pay deal, still lives in a council house if I remember correctly?) all the money whilst paying lip service to those at the bottom. I also don't want to fund politics, and certainly not Labour.
Sorry for the rant, but I've seen unions be destructive and not care a damn about the people they are supposed to protect.

To drag this back on topic, I'm driving 495 (Y437 NHK, Trident/ALX400), and I've noticed something unusual about it; unlike the rest of the ex-Stagecoach Tridents we've had delivered so far, it's fitted with a ZF 5HP500-series gearbox (the rest have Voith 3-speed 'boxes).
Can anyone shed any light on why this particular one is different?
