For around ten years, systems of share ownership, profit-sharing and employee savings have become widespread. In 2010, 8.8 million salaried employees were working in a company that had put in place at least one of these mechanisms and among them, 7.2 million earned a bonus through share ownership or profit-sharing or enjoyed a top-up from the employer on the company savings or retirement savings plan. The offer of such mechanism and the amounts distributed are however unequally shared depending on the company, and, consequently, the employees. In all, in 2010 more than half of employees did not receive any bonus in profit sharing and employee savings, while 10% who benefited the most shared 57% of the amounts distributed under the scheme. The size, the sector of activity and the average salary in the company are the factors that most determine access to these mechanisms and the amounts received.
