Thousands of civil servants will stage strikes over the next few days as part of a three month long campaign of industrial action over pay, pensions and conditions.
Members of the Public and Commercial Services union (PCS) at public and regulatory bodies including Ofwat, Ofgem, the Food Standards Agency and the Equality and Human Rights Commission will walk out for an hour from 11am tomorrow, Thursday and Friday.
The union said around 12,000 of its members in more than 30 different organisations will be involved in the strikes.
PCS is embroiled in a bitter row with the Government over a range of issues, including jobs and pay, and has held a series of stoppages in recent weeks.
General secretary Mark Serwotka said: "The Government's u-turn on the equality duty, the horse meat scandal and the cold winter leading to massive utility bills, all highlight the importance of these bodies to our lives.
"These essential public services, often unnoticed and underpraised, should be well resourced and left to do their work, instead of facing cuts and denigration by ministers who shamefully claim they are cutting 'red tape'."
