The union said it was “bitterly disappointed” that no buyer could be found for the business.
Lawrence Wason, the union’s divisional officer, said: “We’re now faced with the loss of around 1,700 jobs from the factory with the devastating impact this will have on individuals, families, the local economy and Scotland itself.
“Generations of families will be hit by this closure and it is a sad day for Scotland. I think the company’s ultimately responsible for the state it find itself in. There’s a long-serving workforce there, which is very skilled, and they’ve done everything they possibly can, industrial relations have been good on an ongoing basis.”
Neither proved viable
Vion UK chairman Peter Barr confirmed that the firm had received two offers for the Hall’s of Broxburn site before Friday’s deadline but neither proved viable.
“Regrettably, having reviewed both offers over the weekend, we have been forced to conclude that neither of these proposals constitutes a viable and sustainable alternative to the proposed closure of the plant,” said Barr.
“In neither instance were we assured that either offer provided a guarantee of ongoing employment for the workforce, in spite of the fact that VION was prepared to offer substantial financial assistance to support the acquisition.
“This is a very sad day for the company but, unfortunately, the plant continues to suffer unsustainable losses of £79,000 a day. Consequently, it is with great regret that we can confirm that it is our intention to proceed with plans for a phased closure of the plant.”
Some areas of Hall’s will cease production later this month with full closure expected to take place by next February.
Both Wason and Scottish government finance and employment secretary John Swinney pledged to work to mitigate the effects of the closure.
Wason said: “We will now be working with the company to put in place facilities to help the workforce seek alternative employment and secure the best possible redundancy terms to help cushion the blow of such massive job losses.
“We have also met West Lothian Council representatives to explore the ways in which help and support can be offered to the workforce over the coming months.”
Swinney said: “We are deeply disappointed that Vion have been unable to accept either of these bids and have now confirmed the decision to close Hall’s of Broxburn.”
He described the rescue package put together by the Taskforce set up to save the plant as “a strong and creative investment proposition”, which was backed by the public sector.
But he added: “The work of the Hall’s of Broxburn taskforce will continue. The Scottish government, its agencies and West Lothian Council will work together to find alternative employment for all those affected by this decision and to develop opportunities to enhance the wider West Lothian economy.
“I have today confirmed to West Lothian Council that the Scottish government will partner in the economic regeneration of Broxburn and officials are developing plans which we will bring to the Taskforce at the end of October. These plans will help to mitigate the impact of this closure on West Lothian as a whole.”
