First things first – if you're planning on taking the Paris Metro or the RER A train line on Thursday then you won't need to worry.
Neither of these will be affected by Thursday's strike, according to previsions Paris transport chiefs RATP.
The strike which has been called by the CGT union on behalf of workers at the capital's transport operator RATP. Buses and trams will also be normal, or close to normal.
The RER B, which serves the two airports in Paris, will be affected, however.
Basically, only three quarters of trains will be in operation heading from Gare du Nord to Saint-Rémy, Massy-Palaiseau and Robinson.
Northbound trains from Gare du Nord, on lines to Mitry and the CDG airport, will only be running at one third of their normal rate (see tweet below).
The RER C line, which crosses Paris from the northwest to the south, will only 40 percent of trains running.
Lines D, E, H, L and U will see only a third of their RER trains functioning.
Travellers on N and J will see half of their trains in circulation, while there'll be only a quarter running on like K, and 40 percent on line P. Line R will see just one in ten trains running.
There are real time updates via the RATP here.
Public transport workers are striking in protest of their pay and their working conditions, but are also against the new labour reforms.
Recent days have seen action from many other groups in the face of the labour laws, which have prompted strikes from national rail operator SNCF, national airports, and fuel depots.
“This week will see the strongest mobilisation in three months” of strikes, the head of the powerful CGT union Philippe Martinez said on Tuesday.
Since March, hundreds of thousands of people have taken to the streets in demonstrations that have frequently turned violent, while petrol pumps ran dry last week due to blockades of refineries and depots by CGT union activists.
Although most have been cleared, workers at an oil terminal in the northern port of Le Havre — which supplies kerosene to Paris's two main airports — extended their blockade into Wednesday.
