Fifty-two percent of members voted in favour of a strike, while 72 percent voted in favour of industrial action short of strike action.
Kevin O'Gallagher, Unite national officer for IT and communications, said: "This ballot result reflects that our members are prepared to vote 'yes' to back strike action against the company's victimisation of Unite rep and co-worker, Alan Jenney, who is being unfairly singled out. Unite is one hundred per cent behind its members at Fujitsu."
Fujitsu said in a statement: "We are aware of the union's intention to strike following a ballot by members, but we are not able to comment on any specific cases regarding an individual member of our staff."
