Civil servants are set to strike tomorrow bringing disruption to services in Calderdale.
Almost 20,000 members of the Public and Commercial Services Union across Yorkshire and the Humber are expected to stop work.
Contingency plans are in place at Calderdale Magistrates’ Court which will merge workloads and operate two courts.
Jobcentres and tax offices are also among workplaces likely to be affected.
And, the union warned of further stoppages including a second strike on April 5 unless the Government agrees to talks.
PCS Regional Secretary, Juanita Charles said: “We will follow up our budget day strike with a walkout on April 5 and step up our campaigning for the government to take serious action against wealthy tax dodgers.”
A series of rallies take place tomorrow to coincide with the strike at Leeds, Bradford, Barnsley, Huddersfield and Sheffield.
