I initially put "strikebreakers", then I changed it to "scabs" as more people might be familiar with that term, then I changed it yet again to put both terms to be extra clear.

I wasn't aware that "scabs" is more of a derogatory term than "strikebreakers", but then the idea itself for me is derogatory so maybe I'm not the best person to judge.

FWIW: I changed the title to just have "strikebreakers" in it now.
