London Underground strikes

London Underground strikes refers to the industrial action organised by trade unions which affect the London Underground rapid transit network. Described as "one of Britain's most strike-prone industries", trade unions, predominantly the National Union of Rail, Maritime and Transport Workers (RMT), which represent workers on the network, and Associated Society of Locomotive Engineers and Firemen (ASLEF), which represent Tube drivers, have launched strikes in response to disputes over job reductions, pensions, pay, safety, and working conditions.
