Workers at Tata in Port Talbot are to strike after the company ended negotiations over changes to the business which will result in 2,800 direct job losses. Negotiations between unions and the Indian steel giant have today ended at a meeting in London, formally closing any chance of an alternative plan put forward by unions being adopted.

The company will end blast furnace steel production at the Port Talbot plant and will build a £1.25bn electric arc furnace, recycling scrap steel. The º£½ÇÊÓÆµ Government has contributed £500,000 grant towards the plan saying it was the only way to secure any jobs.

We understand the company will close blast furnace five in June and blast furnace four in September. Tata says that its plan will be the largest investment in the country's steel industry in decades and secure the future of º£½ÇÊÓÆµ steelmaking, protecting the "majority" of jobs and reduce the º£½ÇÊÓÆµ's carbon emissions. But they say it is not viable.

"However, the unions' own analysis shows their proposal would cost the company at least an additional £1.6bn when it is already losing £1million a day. Their plans are also high risk and would jeopardise the transition to green steel making,"

A ballot of Unite members, said to total 1,500 across Port Talbot and Llanwern, has already taken place with industrial action being one option. Now, as talks with the company have broken down, the union has said strikes will be announced soon.

A ballot of Community members, the biggest union of workers at the site, is ongoing with a result expected on May 9. The GMB is also consulting its members. No strike action is expected before all the members in all unions have voted.

Community's national Officer for Steel Alun Davies said: "This is an incredibly disappointing day for Tata steelworkers who have been betrayed by a company which owes them so much. It is disgraceful that Tata Steel have chosen to pursue a discredited, bargain basement deal over a viable plan for decarbonisation which would protect jobs and preserve the country's primary steelmaking capacity."

"I know that many of our members will be feeling dejected and anxious today, so it's vital we stick together to look after one another in these uncertain times. It's also vital that we take a stand together and send a message to Tata that we will not go quietly into the night. As someone who has had the privilege of working at Port Talbot and Llanwern, I know first-hand how steel is part of our lifeblood here in south Wales. If the company think that we'll let them trample over our industry and our communities now, they really don't know us at all."

Unions have put forward an alternative plan to the one the company is pursuing but the Indian steel giant has said it is unviable. The º£½ÇÊÓÆµ Government has put money into Tata's scheme, saying it is the only way to secure any jobs at the site.

Community General Secretary Roy Rickhuss said: "We do not accept the company's assertion our plan was too expensive - in fact, it would have returned the company to profits, and the additional capital expenditure needed to make it a reality could have been funded by an additional £450m from the government - a drop in the water compared to what other European countries are investing in their domestic steel industries.

Unite has described Tata's poverty pleading over its º£½ÇÊÓÆµ operations and its claim that alternative options for Port Talbot are not feasible as a sham.

Unite general secretary Sharon Graham said: "Tata is an immensely profitable company using our outgoing government's inadequacies to make easy money and boost its other operations at the expense of º£½ÇÊÓÆµ jobs and the national interest."

"Why else would it be rejecting the promise of £3 billion for º£½ÇÊÓÆµ steel investment from an incoming Labour government and turning its back on a location ideally placed to reap the rewards of a steel market projected to grow tenfold?"

"Our current government has utterly failed to stand up to Tata and demand better for Port Talbot and Llanwern's steel communities and the country. Tata's workers, with Unite using every power at its disposal, will not so easily be defeated. It's plans will be answered with industrial action."

Jo Stevens, Shadow Welsh Secretary, said the news consultation had ended is a "gut punch". "This is a total gut punch for people in Port Talbot, and the potential economic consequences will reverberate across south Wales for years."

First Minister Vaughan Gething and Welsh economy minister Jeremy Miles have said: "Quality steel, made in Wales, is the economic bedrock for many communities across Wales and is vital for the economy and security of the º£½ÇÊÓÆµ."

"We have consistently argued that there is a better deal for the industry and Tata workers that could and should be struck - securing a longer, fairer transition towards the greener production of steel in Wales. The Welsh Government will continue to make the case for that fairer transition and do all we can to support the skilled and loyal workforce and those in the supply chain. We will be reaffirming this commitment this afternoon to the transition board."

Welsh secretary David TC Davies said any strike action was a matter between unions and the company. "I think it was inevitable Tata was going to close the blast furnaces because of the losses they are making. We don't want disruption to the supply chain."

"People feel very strongly about this and 2,800 people face losing their jobs so I understand why they are angry and upset however I don't want to get into taking sides."
