Workers have been on strike for nine weeks

They have said that they are prepared to take their fight to the courts if they have to.

At a meeting at Caernarfon Football Club on Tuesday workers voted unanimously not to end their long-running industrial action.

They have been on strike for nine weeks after a dispute with the factory's American owner over plans to change their working practices - including a cut in wages of 15%.

Workers had planned a series of week-long stoppages but at the end of the first five days of action, management decided to lock them out of the plant.

Since then, staff have been manning pickets outside the factory gates while a number of temporary workers have been hired by the company to do their jobs.

Despite several attempts to resolve the dispute by the conciliation service ACAS both sides remain in a bitter deadlock.

Earlier this month a meeting between managers at the plant, union representatives, and mediators failed to bring an end to the industrial action.

The strikers were sent letters saying they must agree to the changes in their working conditions by Tuesday afternoon and return to work on Wednesday or they would be fired.

Dafydd Wigley AM: 'Appalled' at management's position

Local AM, Plaid Cymru's Dafydd Wigley, said he believed the workers were being treated "appallingly".

He said management were not showing any form of compromise, and he had very grave doubts about the future of the plant.

"The way things are going is on a downward spiral"

"If these men lose their jobs and others are brought in, I worry for the future of the plant," said Mr Wigley.
