SeAH wind has claimed that GMB Union’s pay demands are “unaffordable and unrealistic” after the trade union threatened strike action at the fabricator’s Teesside monopile facility.
A spokesperson told reNEWS: “SeAH Wind regrets that its latest offer, independently benchmarked and designed to be both fair and sustainable, has not been accepted by the GMB Union.
“We are particularly disappointed that the union has chosen not to initiate the dispute resolution procedure outlined in the collective agreement recently signed by both parties.”
The comments come in response to GMB claims on Thursday that more than 150 workers at SeAH Wind’s facility will strike if talks over shift allowances and a pay offer break down.
Prior to GMB’s formal recognition, SeAH Wind implemented a 3.1% annual pay increase for all employees in May 2025, backdated to April, SeAH said.
SeAH also pointed to discretionary bonus payments in March of £500, or £1,000 for employees with more than three months of service.
The fabricator claimed GMB’s demands of a further 12% pay increase, further enhancements to shift allowances, and four additional days of paid leave for medical and dental appointments are “not financially viable given our current business position”, a SeAH spokesperson said.
“To date, we have not delivered a single customer order, and delays have significantly impacted our deliverability for the remainder of 2025,” the spokesperson said.
“As a result, we are incurring substantial operating costs and do not expect to reach a sustainable cash position until late 2026.”
