Sorry, that is not an accurate description of the issue. These unions are pushing back against technology improvements.
——Some union members also complain that technology itself jeopardizes jobs by automating some of the work previously performed manually by workers covered under old union contracts.
This has been a long standing effort of those Port Unions to avoid modernization.
——Technology emerged as a sticking point as the International Longshoremen’s Association and Atlantic and Gulf waterfront management entered a second day of discussions on a possible contract extension of their coastwide master contract.

The combination of automated and manual crane operation results in a faster transfer, Harris said. For example, the Portsmouth terminal operates at a rate of 45 container-moves per hour, compared with a nationwide average of 35 to 38 moves.

I haven’t been involved on the docks in a number of years, but 30-35 moves per hour is flat out flying for a single crane operator, and the crews on dock, and aboard ship per crane, per hold, in feeding the hook. The hook is the focus.
Perhaps a couple of cranes, and a couple of crews on, and off the vessel are involved with that 45 moves per hour figure.
There’s much involved in loading, and unloading a vessel, and somebody getting creative with their figures for whatever reason isn’t of benefit to the industry overall.
