Renault is reducing its Laguna production from two shifts to one following lower than forecast sales.
The carmaker this week announced plans to cut 6,000 jobs in Europe, mostly in France.
This will include 1,000 cuts at its Sandouville plant, where Laguna production will reduce to a single shift.
That prompted a call from the CGT union for a one day strike today at all Renault plants in France.
British assembly plants for Toyota and Land Rover recently announced temporary reductions in production while re-balancing stocks to demand.
However those measures involve no job losses, as staff will undergo training during the downtime.
