Today's strike, for the first time, is ordered by the RMT over pay and the disciplining of its union officials employed by SWT. Previous stoppages have been just about pay - though the effect has been the same with the Stagecoach-owned company, which carries 350,000 passengers a day throughout southwest London, Surrey, Hampshire, Wiltshire and Dorset, managing to run only between 10 and 15 per cent of its usual 1,700 services.
