To be fair, I think the public bristled at the longshoremen strike because the vast majority of their leverage comes not from (most) of their jobs being particularly high-skill but from the fact that they can unilaterally destroy the entire economy for everyone else. Add to that the fact that their union chief was extremely blunt about the whole thing, and that longshoremen make, on average, triple the average household income in the US, it wasn't a very sympathetic cause.
