Driving examiners and Rural Payments Agency workers begin a series of strikes by civil servants across England, Scotland and Wales on Tuesday.
The members of the Public and Commercial Services union (PCS) will be followed by those working for the National Highways, the Border Force and a number of offices in the Department for Work and Pensions in the coming weeks.
Around 100,000 PCS members working in 214 government departments and other bodies have voted for strike action over pay, pensions, jobs and redundancy terms.
