French President Emmanuel Macron's government is launching an effort to redesign labour rules, one of the most important and divisive promises of his presidency.
Labour Minister Muriel Penicaud told RTL radio that the government is "moving the rules of the game" in hopes of tackling unemployment, hovering near 10%.
A draft labour law is being presented at a Cabinet meeting on Wednesday, and unions fear it will remove hard-earned worker protections.
The government proposes to cap the financial penalty for companies sued for firing employees, and to allow businesses more flexibility to define internal working rules.
The government wants to use a special procedure to pass the measures this summer without extended debate in parliament.
Ms Penicaud, a former director of human resources for food-products multinational group Danone, said the reform is "expected by the French, they gave a clear signal of need for change" by electing Mr Macron, a pro-free market centrist.
She insisted the bill could be amended and the government is not signing itself a "blank cheque".
A total of 48 meetings with workers unions and employers' organisations are scheduled to discuss the reform, she stressed.
The CGT union called for a national day of protests and strikes against the labour reform on September 12.
