Technology giant Hewlett-Packard plans to cut more than 1,100 jobs at a number of UK sites in the new year including in Warrington, according to union leaders.
Unite said the US-based firm will axe 1,124 posts in Bracknell, Sheffield and Warrington, as well as among staff who work from home.
Unite said 618 jobs could be lost at the Bracknell hub, although the employees work at multiple locations; 483 will go at Warrington and 23 at Sheffield.
The union claimed the company was a "long-term addict to a culture of job cuts", adding that its European managers had little autonomy.
Unite said the company blamed falling demand and reorganisation for the job losses it wants to implement in the first three months of 2014.

"For the last five years HP has been addicted to a culture of job cuts in the UK to such an extent that its highly skilled workforce has little faith in the way the company is being managed and will be going forward.
"Unite will be doing everything possible to mitigate these job losses which are a hammer blow to the UK's IT sector and very distressing for employees in the run-up to Christmas."
