The UK’s largest civil service union, the Public and Commercial Services Union (PCS), has picked Budget Day – 20 March – to start its industrial action over pay and pensions.
The day will be the first in a series of protests which are scheduled to last three months.
The union’s members, who include Jobcentre, benefits and tax office workers, want a 5% pay rise, or £1,200.
The PCS says 61% of those who voted in a national ballot opted to strike.
Turnout among the union’s 250,000 members balloted was 28%.
Of those who voted, 80% were in favour of forms of industrial action other than striking.
