French businessman Jean-Luc Petithuguenin employs more than 4000 staff, comprising 52 different nationalities, in his recycling business located in Seine-Saint Denis, the immigrant and Muslim heart of Paris.

The politically active CEO of Paprec, which counts 50 factories across France, has come up with a novel way of responding to rising political and religious extremism in France: a charter of secularism (laïcité) in his workplace. The charter, which was signed unanimously by staff and management, says it is the “duty of the employee to remain neutral when it comes to religion.” “Secularism at the company guarantees employees a common and shared reference, favoring cohesion of the company, respect for diversity and collective harmony…the wearing of all signs or clothing by which staff ostensibly manifest religious affiliation is not authorized,” the charter says.

In practice, that means banning visible signs of religious belief—such as the Muslim headscarf, known as the hijab—as well as prayer rooms.
