I don't know if the transport companies settled their differences and now have a multi year contract resulting in a strike free 2019 or if this starts over again like an unpopular seasonal event each spring. Maybe those who live in or travel yearly in France can shed some light on this.
Well, the Unions and the Government and the SNCF have entered an uneasy truce ; and whilst there might always potentially be some strike action in 2019, concessions on all parts have been made, and I'm unsure as to how much stomach for "struggle" remains in the grassroots Union membership.
There are some strikes that seem to follow the patterns of the football (soccer) season, but these tend to be localised mostly in Paris and some other large cities, leaving most of France and most TGVs and Intercity trains mostly unaffected (last year's strikes were a significant exception to the general rule).
Having said that, these were NOT the worst transport strikes I've ever witnessed -- the 1995 strikes lasted about a month, and there was basically 95% of all public transport throughout the whole country at a standstill. (I believe the 1968 strikes were even worse than that)
That month, I would walk to Univ in the morning and back home in the evening, in bitter cold and often chilling rain, sleet, or snow (the snow was the easiest), as most had to do, or cycle or rollerblade or skateboard, as petrol (gas) delivery to keep your automobile running was extensively disrupted too. The mean winter temperature in Paris
intra muros descended that year to rural levels, because of the near absence of motor transport in the city. (One of the rare positives of this was that, on a clear night, you could have an excellent sight of the stars, right bang in the middle of one of the most important cities in the world) About 90% or more of the students at my Univ were unable to attend the courses and seminars, which carried on regardless because
hey !! it's the
Sorbonne and
débrouillez-vous ...
very few professors or tutors cancelled any of their classes, regardless of the strike, although many of the more liberal-minded establishments did exactly that.
The 2018 strikes were quite gentle in comparison, though if you were unlucky enough to have made reservations for a strike day that was also a start or end of holiday date, and you weren't travelling alone, and the train seat you reserved was on a cancelled train, well, that meant no space on the train for you ...
But really, I just can't see anything even resembling any of that horror scenario in 2019 ...
