A leaked Department for Business, Innovation and Skills (BIS) document shows that Tory business minister Sajid Javid plans to cut thousands of jobs.
Some 14,000 people work in the sub-departments lined up for the cuts and 40 percent of these jobs are at risk.
The cuts would slash £100 million more than even chancellor George Osborne demanded.
Over 10,000 of the workers are outside London and the plans include moving some regional offices to London.
Civil service workers in the Sheffield BIS office began a ballot for strikes last week over plans to move the office to London.
The leak shows that the attack will be replicated across the country. Workers in Sheffield must vote for the action needed to stop it.
PCS needs to ballot its members for strikes against the cuts immediately.
