STAFF working for offshore wind giant Orsted at two sites across north-west England are set for strike action over pay, their union has announced.

Workers based at the Danish-owned company’s sites in Birkenhead, Merseyside and Barrow-in-Furness, Cumbria, will begin a 48-hour strike on Friday, the RMT said.

The dispute, which will include a further two-day walkout beginning on September 30, follows what RMT branded a “paltry” below-inflation wage offer of just 3.5 per cent for employees in the operations team.
