There are three live strike ballots at IT company Fujitsu after ballot results last week.
IT workers in Manchester, organised by the Unite union, voted by 56 percent for strikes.
The union describes the dispute as “a breakdown in industrial relations, company union-busting and breaches of agreements”.
Management and workers were due to meet with the Acas arbitration service on Tuesday.
Workers in the PCS union who provide IT services to five government departments could also strike.
Some 65 percent voted for a strike over an “insultingly low” pay offer.
The offer will mean rises of between just 1.5 percent and 2.5 percent. The lowest paid staff earn just £13,500 a year.
Sites affected include Revenue and Customs in Telford and Netherton, Merseyside, and the Driver and Vehicle Licensing Agency in Swansea. Other sites for these departments will be hit, as well as the Home Office, Ministry of Defence and Office for National Statistics.
PCS general secretary Mark Serwotka said, “These staff support essential public services and it is time ministers stopped washing their hands of issues like low pay among their contractors.”
The third dispute is to defend Alan Jenney, a victimised Unite rep. Workers in Crewe first took action in his defence on 30 June to coincide with the public sector pensions strikes. Messages of support have come in from across the trade union movement.
The PCS and Unite unions signed a cooperation agreement at the PCS conference in May.
There is an opportunity for coordinated action in Fujitsu in September—and to link up with the public sector pensions fight.
