Fujitsu workers lobbied parliament today to highlight their ongoing dispute over jobs and pay today.
Meanwhile, a spokesman for Fujitsu said that there were still no talks planned at present.
The workers are fighting a pay freeze, the closure of a final salary pension scheme and 70 planned redundancies by the end of January.
Police initially tried to block a photocall of around 20 Unite union representatives from Fujitsu sites around the UK in front of Parliament, though workers were eventually able to meet with their constituentcy MPs and put forward their case.
Peter Skyte, Unite national officer for the IT sector, said: "We urge Fujitsu now to work with us on settling this dispute in the interests of the company, the workforce and our members."
Last week, the House of Commons tabled an Early Day Motion by Tony Lloyd MP in support of the workers, calling for Fujitsu and Unite to negotiate a settlement to resolve the dispute.
At the same time, Fujitsu workers across the UK gave notice of five days of strike action between 22 January and 8 February, affecting contracts ranging from those with Marks & Spencer and Vodafone to HM Revenue & Customs and the Financial Services Authority.
The move follows on from a five-day strike by members of the Unite union which took place in early January.
There was also a one-day walkoutin December, marking the first ever national strike at an IT company.
