Prysmian Cables Wrexham workers hold pay strike

Prysmian Cables won a contract to supply cables to the Gwynt y Môr wind farm off the north Wales coast

Around 400 workers at a north Wales power cable factory have gone on strike over a pay dispute.

The six-hour strike at Prysmian Cables on Wrexham Industrial Estate began at at 13:00 BST. Night shift workers will strike at 01:00 on Thursday.

The Unite union said it had been negotiating since February but had been unable to reach an agreement.

The Prysmian Group said it wanted talks but the union had refused to suspend the action.

"It's an ongoing pay dispute," said Unite regional officer Tony Brady.

"Negotiations started in February/March but the company has not met the expectation of the membership.

"We balloted for industrial action and the membership voted 94.7% in favour."

Further industrial action, along the same lines, would be held on Monday, said Mr Brady.

A Prysmian Cables spokeswoman said: "We've been keen to talk with the union to resolve the dispute and have engaged Acas to try to support this process.

"Unfortunately, the union decided it wouldn't meet the company unless it could also carry on with the strike."

She said it was unfortunate the union refused to suspend the strike in the meantime.

In 2010 Prysmian Cables won a £15m contract to manufacture and install power cables to the Gwynt y Mor windfarm off the north Wales coast.
