Fujistu staff in Crewe and Manchester are staging a 24 walk out on Monday in a strike over victimisation of Union representatives.
Unite members at the IT services firm voted to take strike action after one of the union reps was made redundant and sparked off a debate about deliberate targeting of union staff.
The case, which has been rumbling on throughout the summer, focused on the redundancy of Unite rep Alan Jenney who had worked at Fujitsu for 17 years.
Despite negotiations between union and Fujistu management a resolution couldn't be found and so from one minute past midnight on Monday morning the staff start a 24 hour period of industrial action.
Kevin O'Gallagher, Unite national officer, said that the agreements made with management over union recognition appeared to have been broken by Fujitsu.
"Workers at Crewe have said they will not stand by and allow their rep and colleague Alan Jenney to be victimised in this manner by Fujitsu and will stand by him all the way until his situation is resolved, as will his union Unite," he said.
"This company has shamefully failed to honour the agreements made with the union and our members feel they have no option but to take industrial action," he added.
Already there have been warnings sounded in the channel that with public sector cuts biting and more redundancies happening across the services industry there could be more industrial action.
The fears are that the contracts that the like of Fujitsu handle could be negatively impacted by the strikes.
