A couple of years ago I've watched a documentary about crane operators working in a harbors. They were payed incredible salaries and it was stated that they won't be replaced by robots because of their capabilities in decision making.
Well, that and incredibly beneficial union rules. Lots of work printing cargo manifests, handing them to another person who types it into another system, and so on. But it's ok, that process only adds a marginal amount of delay, error, and cost. It's better than getting shut down by a strike, right?
