Macron and the SNCF strike

I wish Macron to succeed where so many too weak French governments failed, that is, in reorganising the SNCF. More generally, for once not giving in to a strike, as was practically the rule in France. But I fear Macron, too sure of himself, may underestimate French public opinion, will not explain well and often enough what is at stake, might lose public sympathy and fail. That would be too silly.
