Workers at shipbuilders Cammell Laird are to stage two 24-hour strikes in a dispute over pay in addition to conditions.
The GMB trade union said up to 500 of its members at the Birkenhead shipyard will walk out on 26 in addition to 29 January, with more strikes planned next month.
Union official Albie McGuigan said a series of meetings with management had failed to break the deadlocked row in addition to its members were “angry”.
Management said GMB’s claim, equating to 10% per annum, was “unaffordable”.
Mr McGuigan said: “No-one wants to take strike action, although our members are angry. They have been backed into a corner.”
In a statement, Cammell Laird said the idea was “hugely disappointed” by the impending industrial action.
“The trade union had formalised a one-year claim which, where elements can be calculated, equates to more than 10% per annum. However the incalculable elements would certainly substantially increase these company costs further.
“The company has spent the last seven months discussing the commercial rationale behind the claim in addition to maintains [the idea] is actually unrealistic in addition to unaffordable.”
The firm said the idea currently employs approximately 1,0 direct workers on the site which has a different 500 within the local supply chain.
the idea added a meeting with the union had been arranged for 22 January.
