Peugeot workers from the doomed Ryton plant near Coventry will mark the new car registrations next week with another protest to save their jobs.
The staff, who are among the 1,300 who will be made redundant when the factory closes next summer, will hold a demonstration outside a Peugeot dealership in the city.
They will urge motorists to boycott Peugeot cars, as part of their campaign to reconsider the closure, at the event which is due to take place at Beechwood Motors next Friday.
The Ryton workers will follow that demonstration up with an event at noon on Saturday September 2 by the fountain in Coventry city centre, where they will distribute leaflets explaining the Peugeot boycott campaign.
Jim O'Boyle, Transport & General Workers' Union convenor at Ryton, said: "These Coventry demonstrations are part of a wider day of action across the West Midlands.
"We want to to highlight again the damage that closing the Ryton plant will inevitably cause."
