Labor Day in France will see workers against a law raising retirement age to 64 resume protest against President Emmanuel Macron who signed it last month.
Unions and the opposition are hoping for a mass turnout on Monday to let Macron know they continue to oppose the pension overhaul.
The day will mark the first time since 2009 that all eight of France’s main unions have joined in calling for protests.
Labor unions early last month walked out of talks with prime minister Elisabeth Borne after she refused to budge on the pension reform’s headline measure of raising the retirement age from 62 to 64.
France has been rocked by a dozen days of nationwide strikes and protests against Macron and his pension changes since mid-January, some of which have turned violent.
But momentum has waned at recent strikes and demonstrations held during the working week, as workers appear unwilling to continue to sacrifice pay.
Protests in recent weeks have taken on a more humorous tone.
Demonstrators clanged kitchenware to drown out Macron during a speech to the nation after approving the pension law last month, and activists have kept up the practice on some of his visits around the country.
Near the Stade de France stadium outside Paris on Saturday, union activists distributed red cards and whistles to football fans coming to watch the final of the French Cup.
