Unite has announced members working for Fujitsu in Crewe will take further strike action this month in their long-running row over jobs and pension cuts.
Along with workers at 10 other UK sites, they'll be walking out for 24 hours on April 13th and 24th.
There will also be a 48-hour strike starting on Thursday 20 April.
The dispute centres on pay, pensions, job security and union recognition.
It follows an announcement by the IT giant last year that up to 1,800 UK jobs could be lost as part of plans to streamline operations.
Unite says the 'ill-considered move' jeopardises the viability of the existing business and runs contrary to its image as a ‘responsible business’.
Unite national officer Ian Tonks said: “The previous four days of strike action generated strong support from workers determined to stand up for their jobs and livelihoods.
“The way Fujitsu is treating its workforce and keeping them in the dark over its plans for the future is beyond contempt.
“This is a workforce that has worked hard to make Fujitsu in the UK highly profitable, yet their reward is job cuts and pension reductions, while the company frustrates Unite’s attempts to minimise compulsory redundancies.
“Fujitsu needs to start seriously engaging with Unite to avoid further industrial action, which could stretch into the summer.
“It is in danger of suffering severe reputational damage and will no longer be able to masquerade as a ‘responsible business’.”
