NORTH Sea oil and gas workers could bring production to a grinding halt in the biggest offshore dispute in a generation, after voting overwhelmingly in favour of strike action.

Unite has received overwhelming support from members to organise against four companies key to oil and gas industry majors’ ability to function in the North Sea.

Ballots across Bilfinger, Stork, and Wood Group UK all delivered over 90 per cent in favour of strike action, with the ballot at Petrofac securing 100 per cent support.
