More than 1,100 workers at Hewlett-Packard’s UK facilities will be made redundant in 2014, according to Unite union representatives.
The job cuts will affects factories in Warrington, Bracknell and Sheffield, as well as some ‘work from home’ positions.
Unite said, the electronics manufacturer named falling demand and reorganisations as the reason for the redundancies.
The job cuts will be implemented in the first quarter 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,” said Unite national officer Ian Tonks.
"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."
HP said in a statement it commenced consultations regarding UK workforce in the 2014 at the end of November.
"The proposed UK workforce management plan is part of HP's global multi-year productivity initiative that was announced on 23 May, 2012, and updated at its securities analysts meeting on 9 October, 2013, to address current market and business pressures in support of HP's turnaround,” the company said.
"HP remains committed to supporting the employability of its employees through a number of internal initiatives, including re-skilling, redeployment and support to obtain alternative employment as appropriate."
