Term strikebreaker Definition: Someone who starts working or continues to work for a firm while a labor union is engaged in a strike of the firm. Strikebreaker is the polite name for such a person. Striking union members are more inclined to use the term scab (or something even more derogatory). As the name strikebreaker suggests, such workers are used by employers to force union members to stop their strike and return to work. While strikers don't like it, labor laws guarantee that nonstriking workers can cross the picket line and go to work.
