Unions have condemned Tata Steel's plans, which are anticipated to involve closing the bulk of its operations at the UK's largest steelworks, the Port Talbot plant.
While Tata's announcement about the plant's future was expected on Wednesday, it has been delayed, and the exact details of the plan remain unclear.
Unions, including GMB, Community, and Unite, have fiercely opposed the anticipated proposals. They have promised to use all available means to oppose them.
The UK government had previously pledged £500 million to keep the Port Talbot site open, with a focus on greener arc furnaces. However, the unions have criticized this plan and called for further consultation and exploration of decarbonization options for the steel industry.
