On this day in 1816 the term "scab" was coined by the Albany Typographical Union in reference to strike breaking. The National Labor Relations Act attempted to make strike breaking illegal. However a Supreme Court decision in 1938 created an opening for replacing workers at the end of a strike and bringing in "permanent replacements" if the union loses majority support.
In British labor history the term scab has its origins in the Elizabethan era.
