No, US longshoremen lost that jobs battle decades ago, Some got settlements that lasted for life, but there were no more new longshoremen. There's a good writeup of this in "The Box", a history of the shipping container by Marc Levinson.

The Port of San Francisco stopped being a freight port because of containerization. A new container port was built in Oakland, using dirt and rock excavated for BART construction. San Francisco lost its freight rail service, and the railroad yard became the Mission Bay development. The San Francisco Belt Railroad closed in 1992. There used to be freight trains on the Embarcadero.

Something similar happened in London. A small non-union port on the east cost of Britain became the main container port, and container ships never made it to London. Not that they'd fit in the Thames River anyway. No more London dock workers.

In container ports, "by hand" means cranes and big forklifts. "Automated" means very few people in the container areas at all.

Port of Antwerp, 2015.[1] That's real, but sped up.
