The RMT union has called up to 4,000 station staff out on strike affecting stations across the city for 24 hours from one minute past midnight.
Shortly after 6am on Monday the Bakerloo, Circle, District, Hammersmith & City, Metropolitan, PIccadilly, Victoria and Waterloo & City lines were closed with the Central, Jubilee and Northern running a special service and the DLR suspended.
The strike is a dramatic escalation of the union’s dispute with Transport for London over feared threats to staff pensions and concerns that the loss of up to 600 station posts will lead to remaining staff having to work more unsociable hours or be left alone in stations at night.
