Members of the Bectu and NUJ media workers’ unions at news provider ITN are set to strike on Tuesday of next week.
The workers voted overwhelmingly to strike over proposed cuts to their pension scheme.
More than 67 percent of NUJ union members supported the strike call as did 60 percent of Bectu members.
ITN management have proposed to make up a 6 percent shortfall in pension contributions by raising the retirement age from 60 to 65.
Other attacks include slowing the accrual rate of final pensionable pay, capping increases to either inflation or 2.5 percent and raising the retirement age by five years to 65.
Paul McLaughlin, the NUJ national broadcasting organiser, said, “The employers must be willing to move if they want to avoid a strike.
“They must understand that action will be taken on that day and programmes disrupted if they continue to refuse to budge.
“We have taken a step towards management in trying to resolve this issue but they have utterly refused to negotiate with us.
“If they agree to discuss our proposals we would consider calling the strike off, but unless they do that the action will go ahead.”
