The new dates bring the total number of strike days announced so far to 20.

Sites affected include Basingstoke, Belfast, Birmingham, Bracknell, Crewe, Edinburgh, London, Manchester, Stevenage, Wakefield and Warrington. 

The company mainly provides IT services to large organisations across the UK including government departments, Marks & Spencer, RBS and HSBC. It also operates a large managed print services department from its Birchwood, Warrington unit that predominantly provides print for HMRC. The site made major kit investments in 2012 to step up its services for the government department.

The Japanese technology company launched “an extended consultation” in October last year on plans to cut more than 10% of its 14,000-strong UK roles with many set to be offshored.

Announcing the proposals last year, the technology giant said they were necessary to remain competitive in today’s market and to “enable it to better support customers in the era of digital transformation”.

While negotiations are ongoing, the business said it will decline to comment further, however cuts are expected to fall across all of its main UK sites, including Warrington.

Unite national officer Ian Tonks said: “The announcement of five days of new strikes demonstrates the determination of our members to fight for their jobs and employment conditions and our adamant opposition to ‘exporting’ skilled UK jobs abroad. 

“The UK management of Fujitsu is intransigent and refuses to engage with its dedicated and hardworking employees. Our members will continue their fight – and the fact that 20 days of strike action have or will be held is a mark of their strong resolution.” 

Unite maintains that the move to cut and offshore jobs is ill-considered, jeopardises the viability of Fujitsu UK's existing business and is contrary to its projected image as a 'responsible business'.
