Some 400 construction workers have been locked out of their jobs for two months.
The workers were building a biofuels plant in Saltend in Hull.
Vivergo Fuels runs the plant for BP, British Sugar and DuPont.
The dispute began when Vivergo cancelled a contract with Redhall Engineering Solutions, the subcontractor that had employed the workers.
The bosses refused to transfer them to a new contractor.
On Friday of last week workers rejected the latest offer from management.
The offer would not have guaranteed the workers employment rights and would have broken the terms of the national agreement for construction.
The workers have taken a principled stand to defend terms and conditions in the industry in difficult circumstances. Last week saw Phil Whitehurst, the national organiser for the GMB, arrested on the picket line under the public order act. He was on his way for talks with management.
Unfortunately, a national construction shop stewards meeting on Monday of this week did not call for a national day of strikes as many of the locked out workers had hoped.
There has been some support for the workers but they urgently need the support of the rest of the labour movement.
