Technology giant Hewlett-Packard plans to cut more than 1,100 jobs at a number of UK sites in the new year including in Sheffield, 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 company has blamed falling demand and reorganisation for the job losses it wants to implement in the first three months of 2014.
Plans were being outlined at a meeting in Bracknell, Berkshire.
