Calls have been made for a “serious plan of action” to support the 337 people affected by Hoover’s decision to close its factory in Merthyr Tydfil.
Assembly Member for the area, Huw Lewis, made the calls after confirmation was made that the plant would cease production on 14 March.
The firm hopes to keep its headquarters and warehousing facility at the site, with around 113 workers remaining.
About 1,200 jobs have gone at four large employers in Wales this week.
As well as the 337 jobs at Hoover, around 300 were lost at the Indesit plant in Bodelwyddan, Denbighshire last week.
A further 440 job losses were announced at Novellis, an aluminium sheet mill in Rogerstone, Newport.
Hoover said a 90-day consultation period had now ended and it will cease production there on 14 March.
It had concluded it could no longer produce competitively priced laundry products in Wales.
Hoover, which began production in the town 60 years ago, announced its intentions last November.
The Italian-owned company said during the consultation, extensive discussions and detailed analysis, including business and financial presentations, took place with all the worker representatives.
“Unfortunately there was no escaping the conclusion that our Merthyr Tydfil manufacturing facility could not produce competitively priced laundry products,” the company added in its statement.
