Tax workers vote for action over job losses Revenue and Customs workers have voted to take industrial action over job losses and privatisation, adding to the disputes facing the Government. The Public and Commercial Services Union said four-fifths of its 55,000 members had backed industrial action short of a strike, and just over half supported walkouts. Mark Serwotka, the PCS general secretary, said: "It makes absolutely no economic sense to cut ever more staff from the very department responsible for collecting the taxes that fund all our public services."
