Joel Robuchon, the chef with the most Michelin stars in the world, has become embroiled in a legal row after a cook at his newest restaurant filed a complaint for harassment, alleging that he suffered "tyranny" in the kitchen.
Franck Yoke, a chef at La Grande Maison, filed a legal complaint on Friday, claiming that the difficult working conditions forced him to quit after two days.
Mr Robuchon hit back by filing a complaint for defamation, saying the claims about La Grande Maison hotel and restaurant in Bordeaux, which opened in December, were unfounded and sullied his name.
The legal action follows an investigation published last week by Francetv Info in which kitchen staff including Mr Yoke complained of 15-hour shifts without a break, verbal abuse and being forced to drink salt water.
"We didn't have the right to take lunch, only a few five-minute breaks," Mr Yoke told the news website.
