That's because the conductors were striking but not the supervisors, though, not because an automated line is inherently immune to striking. I thought line 14 was stopped because of a strike some time ago but it was apparently just because of an incident, it might never have stopped because of a strike indeed. But that just means the employees that manage it don't strike.
