Overview: what to expect on October 2, 2025 in Île-de-France
Paris and its Île-de-France surroundings face a new day of mobilization on Thursday, October 2, 2025. Eight major unions have united to demand social and fiscal reforms across France, protesting the proposed 2026 budget. After talks with Prime Minister Sébastien Lecornu failed to yield concrete concessions, the inter-union movement continues. For transport users, the latest forecasts from Île-de-France Mobilités suggest a calmer day than the September 18 strike, with most of the network functioning normally. The metro and tram network is expected to operate at or near full capacity, and the automated metro lines 1, 4, and 14 should run as usual, given their technical resilience.

Metro et tramway
– Metro: normal to near-normal across most lines; lines 1, 4 and 14 operate sans perturbations.
– Tramway: normal to near-normal circulation, with minor exceptions dependent on local conditions.
Bus
– RATP bus network expected to run normal to near-normal in Paris, in the petite couronne and grande couronne overall. Disruptions are possible in Argenteuil (lines A, B, C, D, F, L, T, 9 and 262) and on Roissy Pays de France routes.
Where the disruption is most felt
The most affected lines are RER D and Transilien R, both forecast to be strongly disrupted. RER E and Transilien lines L, N and U should experience notable disruptions. In contrast, the core metro and tram networks are largely shielded from major interruptions, with RER A and B remaining critical corridors for daily travel across Île-de-France. This pattern marks a contrast with the September 18 disruption, when several metro lines faced chronic stoppages beyond peak hours.
Practical ways to navigate the day
To minimize impact, commuters are encouraged to consider teleworking if possible. Where travel is unavoidable, the automated metro lines 1, 4 and 14 can serve as reliable backbones for movement. Carpooling via apps like BlaBlaCar Daily or Karos, cycling, and micro-mobility solutions offer viable alternatives for short distances, particularly within Paris proper.
Why this strike is happening
The call to action originates from the inter-union coalition, including CFDT, CGT, FO, CFE-CGC, CFTC, UNSA, FSU and Solidaires. They oppose the 2026 budget, voicing concerns over the doubling of medical franchises, the removal of 3,000 public sector posts, and reforms to unemployment benefits, while demanding stronger fiscal justice—targeted increases on large fortunes and very high incomes. The movement continues the broader autumn mobilizations that have marked labor activism in Île-de-France this year.
Protest plans and travel tips
A demonstration is scheduled in Paris, beginning at Place d’Italie in the 13th arrondissement at 14:00 and moving toward Place Vauban near Les Invalides, passing through areas such as Gobelins and Montparnasse. For travellers, checking live traffic apps from RATP and SNCF Connect is essential for real-time updates. When possible, consider postponing non-essential trips, rescheduling meetings to telework days, and planning routes around the most disrupted lines identified above.

Additionally, separate coverage on the same date notes potential impacts on airports, with authorities advising passengers to verify flight statuses. The public sentiment surrounding the budget debates continues to shape this month’s strikes, signaling a persistent climate of labor action across sectors in Île-de-France.
