Workers at the exhaust factory in Wissembourg voted to begin a strike action on Friday.
The company announced to workers that between now and the end of the year production would be wound down and all 181 workers at the site made redundant. Workers called a general meeting and voted for strike action. They voted at a second meeting on Monday morning to continue the action.
Wimetal is a subsidiary of Tenneco, one of the world's largest manufacturers of exhaust systems. The company has some 90 factories in 24 countries. Wimetal's two other factories in France will not be affected by redundancies.
