London Mayor Boris Johnson promised London Underground cleaners the London Living Wage a year ago. He has failed to stay true to his word and these workers continue to struggle along on the minimum wage in one of the most expensive cities in the world. They work in appalling conditions cleaning up vomit, urine, excrement and even after suicides. They also work nightshifts for no extra pay. RMT says to the London Mayor - Boris Keep Your Promise! Give the cleaners the London Living Wage of £7.60 an hour.
