Manufacturing giant GKN is proposing to close a factory making parts for the automotive industry, threatening over 500 job losses.
Unite said it was seeking urgent talks to discuss the future of the plant in Birmingham, which GKN has owned since the 1960s.
It is understood that the factory has been an industrial site since the 1930s.
A spokesman for GKN Automotive said: “Proposing this closure is a difficult decision which has been made despite significant effort and investment over the past 10 years to reduce the high operating costs at the Birmingham assembly site.
“Sadly, an increasingly competitive global market means that the site is no longer viable. Supporting our people is our priority as we consult on our proposals”.
Unite said it has been told the factory will close in 18 months time.
National officer Des Quinn said: “The workforce have been left shocked and angry to learn that management is looking to close this highly viable site.
“Unite is now seeking urgent meetings with senior management at GKN to understand the business case and the logic behind this decision.
“Unite is committed to working with GKN to find a feasible solution, which will keep the factory open and preserve the jobs of this highly skilled workforce.”
