The demonstrations started on 16 March in central Paris and elsewhere in the country, causing police presence to increase.
The UK Foreign Office advised the protests could turn violent and/or continue, and could lead to disruptions to road travel.
Several unions also called for rolling cross-sector strike action from 7 March, with coordinated cross-sector action planned on 23 March.
Industrial action may start the evening before the strike day and run for several days, but localised or sector-specific strikes could occur outside these dates. Industrialised action may lead to disruption to services.
"You should monitor the media, check the latest advice with operators before travelling, avoid demonstrations and follow the advice of local authorities," the FCDO advised.
