Vilage, I'd just like to add that during WWI, asides from mutinies in 1917, which were "solved" by higher salaries, a better permissions system, and better FOOD by Pétain, and low-level strikes, French society remained rather stable. The Socialists, who were the only ones who could have caused trouble, were in the government, so even though they were rather unhappy with the war, they couldn't really criticize the government. With the war lasting so long, of course, the situation would have changed, I can imagine. It's probable a more authoritarian regime would have surfaced, lead by Clémenceau, who received emergency powers in 1918. After a few years of that, I can't really tell. We would need to know more about the situation on the front.
