Shipbuilding in Australia is a case Sunfish might like to consider.
Worked in the shipbuilding industry in Whyalla building bulk ore carriers in the main, but also RoRo car ferries, oil tanker and semi submersible oil rig. It was interesting to see Asian built ships come into port and the different build standard, the clipping of electrical cabling was not up to the standard we employed, ours much more labour intensive, demarcation of trades was a big problem, an electrician was not permitted to do any welding, to have a bracket welded on you had to find yourself a welder who could spare the time, yet as apprentices we were taught welding. As apprentices we were not permitted to strike but when a strike was held the co-operation between trades was enormous, electricians did their own welding. Bloody minded unions had a large role to play in the demise of BHP's shipbuilding, all imported from the UK as that was the main migrant work force source.
