Workers at a large gas terminal on Shetland have voted to strike in a dispute over pay.

Unite is in dispute with Aker Solutions, a sub-contractor for Total UK, which operates the Shetland Gas Plant.

Members of the union will strike on Mondays and Wednesdays from November 20 after talks failed to reach agreement on a wage increase and holiday pay.

Unite Scotland regional officer John Boland said the union has tabled a 4% wage claim and Aker has offered 1%.

Aker said it was disappointed by plans to strike and is "committed to finding a positive resolution to the situation".

Around 80 workers will take part after 92% of Unite members voted for industrial action.

Mr Boland said: "Aker Solutions' management have consistently refused to conduct meaningful negotiations with Unite over wages and holiday pay.

"After nine months of this, the patience of workers at the plant has run out and no wonder.

"So we have served notice today that from November 20 every Monday and Wednesday our members will be on strike in protest at Aker's refusal to do a deal."

The terminal began processing gas from the Laggan and Tormore fields last year and is capable of supplying energy to two million homes, according to Total.

An Aker spokesman said: "Aker Solutions today received notification from Unite the union of planned strikes at Shetland Gas Plant following the rejection of our increased pay offer.

"We are disappointed with the latest course of action, but remain committed to finding a positive resolution to the situation."

Total said the site will continue to operate safely.

A spokesman said: "Safety is a core value for Total and we will not allow it to be compromised because of this strike.

"Despite this strike action Total will be able to continue to operate the Shetland Gas Plant safely.

"Total have identified measures that will ensure safe operations during the strike."
