Vertaling van "really does think that the collective bargaining that collapsed had everything " (Engels → Frans) :

I am assuming he really does think that the collective bargaining that collapsed had everything to do with rail safety and nothing else, and that those 2,800 employees at CN were concerned with rail safety and nothing else.
Je suppose qu'il pense vraiment que la négociation collective qui a échoué portait uniquement sur la sécurité ferroviaire, rien d'autre, et que les 2 800 employés du CN ne se souciaient que de la sécurité ferroviaire, rien d'autre.
