A unofficial picket line is being staged at the Tata Steel plant in Port Talbot this morning after contract workers claim they were replaced by foreign workers on lower pay rates.
It comes a day after 47 contract workers were told their work was coming to an end.
The men claim they have now been replaced by Polish and German workers on lower pay.
Tata Steel say they have not made any employee redundant and a single contract that was been carried out by a German company has now come to an end.
One contract worker - Robert Newton - says he was working at the plant as an insulation engineer for three months and was told the news on Monday when the men turned up after the holidays.
The men, who say they are all members of the GMB union, say they will demonstrate at the plant all morning.
