Reception and security workers at the Louvre went on strike Monday, in order to protest overcrowding and inadequate staffing. A rise in tourist numbers has occurred rapidly- with 20 percent more visitors touring the Louvre each year since 2009. As tourist numbers have increased, staff numbers have actually decreased. Louvre employees, many represented by a union, are demanding that the museum employs more people and introduces regulations that limit the number of people who can tour the museum at a time.
