Why would higher strikebreakers lead to violence?

What was the purpose of strikebreakers?

Strikebreakers, known pejoratively as scabs, are workers who continue to work during on-going strike action. Strikebreakers may be existing workers, those drafted in to plug the employment gap when other workers are striking, or those who cross picket lines in order to engage in employment.

The term "scab" was first used in the 13th century to mean a nasty, itchy skin disease or the crust that forms on a wound. By 1806, the word "scab" arrived at its current meaning -- a strikebreaker who willingly crosses the picket line [source: Lexicon of Labor, Online Etymology Dictionary].
