Workers at the Louvre Museum have voted to strike over working conditions and other complaints. The CFDT union said the vote took place Monday morning with 400 workers participating. The strike has closed the world’s most-visited museum, turning away would-be visitors. A notice on the Louvre's website advised that “the museum is closed for the moment.” The strike follows talks last week between labor unions and government officials, which failed to address all concerns. The recent jewelry heist has intensified worries about security and staffing issues at the museum.
