Police officers deployed during the Paris Olympics will receive bonuses of up to €1,900 ($ 2,050), French interior minister Gerald Darmanin said on Tuesday in reaction to protests.

Police unions worried about working conditions during the Olympic Games from July 26-August 11 and the Paralympics that follow organised protests and work stoppages this month for better pay and guarantees of holiday leave and childcare this summer.

Darmanin wrote to police staff that employees from the interior ministry will receive an exceptional bonus for working during the security operation that is unprecedented in scale for France. Tens of thousands of police officers, thousands of soldiers, and private security staff will be deployed.

"I want your extraordinary investment to be rightly recognised. I want you to know that you can count on me personally," Darmanin wrote.

To compensate their mobilisation, staff who limit their summer leave for the Olympics will receive a bonus of €1,000 ($1,080).

This incentive will rise to €1,600 ($1,730) if they work in an area hosting an Olympic event. Staff deployed in the Paris region, Paris airport border police and international transport services will get an extra €300 ($320) for a total of €1,900.

Darmanin said he wants 100 per cent of staffers to be mobilised from July 24-August 11 but promised that outside this period every employee will be guaranteed at least two weeks off in the period from June 15-September 15.

The security challenge ahead of the Olympics was highlighted when a tourist was killed in a knife attack near the Eiffel Tower on December 2.
