Hundreds of workers walk off Hull construction site over health and safety concerns

Some 280 of the 480 workers put down their tools at the site on Cleveland Street.

Energy Works (Hull) Ltd said the site remained operational and expected a “swift resolution” to the matter.

A statement said an independent health and safety audit undertaken yesterday "confirmed the site is being operated and controlled in a safe manner."

It added: "Despite this, there has been an unofficial action which involved approximately 280 of the 480-strong workforce withdrawing their labour from the site at 10.30 this morning.

"The Principal Contractor, M+W Group, anticipates a swift resolution to this matter, which will see the full resumption of works on site."

Once up and running, the plant will take 250,000 tonnes of mostly black-bin “residual” household waste from councils across the country and convert it into a gas that turns a turbine and creates electricity.
