PARIS -- The Louvre Museum was closed on Monday morning after its employees voted unanimously to go on strike.

Some 400 employees of the Louvre voted "unanimously" in favor of a "renewable strike", according to the General Workers' Confederation (CGT) and the French Democratic Federation of Labor (CFDT).

"Due to a strike, the museum is closed for the day. We apologize for any inconvenience," Louvre said on its social media X.

Workers are demanding extra staff and measures to tackle overcrowding, dealing another blow to the Paris landmark after the jewelry heist in October.

Tuesday is the Louvre's weekly closing day. According to the unions, a general assembly is scheduled for Wednesday.
