The PCS said the walkout will be mark the largest civil service strike for years and signals a “significant escalation” of industrial action after a month of strikes by its members.
It coincides with the Trade Union Congress’s ‘protect the right to strike’ day which was announced on Tuesday in reaction to the Government’s controversial legislation on minimum service levels during industrial action.
A further 33,000 members working in five more departments, including HMRC, are next week re-balloting to join the union’s national strike action.
PCS general secretary Mark Serwotka said on Wednesday: “During the last month, when thousands of PCS members across a range of departments took sustained industrial action, the government said it had no money.
“But it managed to find millions of pounds to spend on managers and military personnel in a failed attempt to cover the vital work our members do.
“We warned the government our dispute would escalate if they did not listen – and we’re as good as our word.
“I am meeting with the Minister for the Cabinet Office, Jeremy Quin, tomorrow – if he puts some money on the table there is a chance this dispute can be resolved. If he doesn’t, then he’ll see public services from benefits to driving tests, from passports to driving licences, from ports to airports affected by industrial action on February 1.”
A Cabinet Office spokesperson said: “We regret this decision and the Union’s rush to disruptive strike action.
“We greatly value the work of civil servants across the country, but the PCS Union’s demands would cost an unaffordable £2.4 billion at a time when our focus must be on bringing down inflation to ease the pressure on households across the country.
“We can provide reassurance that we have comprehensive plans in place to keep essential services running.
“Discussions will continue and we will be meeting with civil service unions tomorrow, including PCS, as part of that ongoing engagement.”
