I have witnessed that and more like optimisation software being disabled to avoid cutting into overtime. Just go take a look at how drivers are paid and where their comp comes from. It’s all public knowledge. Take a look at the recurring reports from the court of auditors or talk with anyone working there.
We are talking about a company in which the two main unions are openly Trotskyist and which has a permanent strike warning by rotating between union to open one in defiance of French law.
This is not drum beating for privatisation by the way (even if all the formerly public French companies I had the misfortune to work for are fairly mismanaged but nothing as bad as SNCF thankfully). I am sure with enough reforms it could work while being public. I mean Singapore manages so it’s not impossible.
It’s just impossible to wonder why France is in such a sorry state after having working for anything publicly managed in France. The French state carves exception for itself in all the labour laws because they know their administration is so poor they can’t respect them.
