Your argument is completely irrelevant. The time doing the doors is almost completely irrelevant. They'll demand a price based on the grief, risk and liability they'd be taking on, be it the doors on most services, or dealing with passengers and passcoms on 'DCO'/DOO services running without an OBS equivalent for operational convenience. ASLEF can ask for whatever they like, whether you like it or not. You correctly recognise in post #4910 that this'll see staffing costs go through the roof, in the short term... Well, no doubt! Why do you think we've been telling you that the 'second man' grade is dead beyond the length of the franchise? Someone will have to pay for the Kings ransom in the long run, and that'll be the ex-Guards. Before you say ASLEF should in that case not get £10k to £15k, don't waste your time. They're entitled to ask for what it is worth to their members, the TOCs will pay it because that is the price of DOO.
Oh please... Pre-1992 staff could be pissed up half the time, safety wasn't a foremost concern in many respects and as such the 'PTI' wasn't even on the radar. Who was getting sacked or prosecuted for dispatch irregularities back then? So much was just able and expected to be brushed under the carpet... With that in mind, plus the much lower pay rates of those days and with far more opportunities and options across the organisation for displaced Guards, how can the situation back then be sensibly compared to the situation now?
