ITV production workers and other staff are to strike on May 14 in a dispute over pay, the Bectu union has announced.
The technicians' union Bectu said its members had voted in favour of industrial action by 67% in protest at a 2% pay award.
Unions have been pressing for a bigger wage increase in view of the TV company's profits.
"There is a huge disparity between the pay offered to staff and the bonus package to executives as well as shareholder dividends," said Bectu general secretary Gerry Morrissey.
"Our members are helping to make the profits but are not sharing in them."
Bectu said the strike, which will coincide with ITV's annual meeting, will hit live programmes and journalists and other staff are also involved in the dispute.
