Staff at IT services company Fujitsu will go on strike for three days this month after union Unite served notice of the action.
A total of 75% of Unite members in the company voted for industrial action.
The union said this is the first national strike in the IT sector.
The strike is in relation to 1,200 planned redundancies, a pay freeze and plans to close the final-salary pension scheme.
Peter Skyte, Unite national officer for IT and communications, said, "We wrote to the Fujitsu UK CEO following the industrial action ballot announcement with the aim of attempting to resolve the issues on jobs, pay and pensions. So far, we have yet to receive any formal response from the company.
