Workers at the Louvre Museum voted Monday to strike over working conditions and other complaints, dealing another blow to the Paris landmark and home of the "Mona Lisa" after an embarrassing jewelry heist in October.

The CFDT said the vote was taken at a meeting of 400 workers on Monday morning and that they decided to strike for the day. Striking workers with flags, banners and placards blocked the museum`s iconic glass pyramid entrance.

The world`s most-visited museum didn`t open as scheduled and turned people away. An updated notice on the Louvre`s website said it was "exceptionally" closed for the day and that ticket holders would be reimbursed.

"It`s really sad, because I was really looking forward to this," said Lindsey Hall, a bitterly disappointed would-be visitor from Sacramento, California. She had been planning to enjoy the museum`s huge collection of art and artifacts with a friend, describing it as "one of those life experiences you crave."

"This is just an epic collection of art and something that every human should see," she said. "I can see the other side of it, like if you are the person that works in the museum and how that can be, like day after day after day."

The strike vote followed talks last week between labor s and government officials including Culture Minister Rachida Dati. Labor leaders said the talks had not alleviated their concerns about staffing and financing for the museum that welcomes millions of visitors each year.

"Visiting the museum has become an obstacle course," said Alexis Fritche, general secretary of the culture wing of the CFDT .

For employees, the brazen daylight jewel heist crystallized long-standing concerns that crowding and thin staffing are undermining security and working conditions at the Louvre.

Police arrests subsequently snared the entire four-man team alleged to made off with $102 million worth of jewels. The gang used a basket lift to reach the Louvre`s facade, forced a window, smashed display cases and fled with pieces of the French crown jewels. A Senate inquiry released last week said the thieves escaped with barely 30 seconds to spare and pointed fingers of blame at broken cameras, outdated equipment, understaffed control rooms and poor coordination that initially sent police to the wrong location.

In a statement, the CFDT said employees want more staffing for security and to welcome visitors, improved working conditions, stable long-term budgets for the Louvre and leadership that "truly listens to staff."

Yvan Navarro of the CGT complained that staff numbers have continually decreased while visitor numbers have increased.

"People come to Paris to visit the museums. So the visitor numbers go up, the tariffs and the prices go up, because everything is becoming more expensive but the salaries and the numbers of staffers don`t go up so obviously you reach a point like today, a day of anger," he said.

Labor leaders said the strike vote was unanimous. It wasn`t immediately clear whether the work stoppage will last longer than one day. The Louvre is closed on Tuesdays. Employees could meet again on Wednesday to decide whether to stay out or go back to work.

In their notice of open-ended strike action to Dati last week, the CFDT, CGT and Sud s said the Louvre was in "crisis," with insufficient resources and "increasingly deteriorated working conditions."

The Culture Ministry said Sunday that it has tasked Philippe Jost, who oversaw reconstruction of Notre Dame Cathedral after its 2019 fire, with a mission to propose a deep reorganization of the Louvre following the findings of an administrative inquiry.

It said Jost will offer recommendations by the end of February. He will work with Louvre director Laurence des Cars, who previously described the heist as a "terrible failure."
