In organized labor, an employee who breaks a strike. That is, a scab does not go on strike with other employees but instead keeps working. A scab may do this out of concern for his/her livelihood, because he/she does not agree with the reasons for striking, or for some other reason. Because scabs are thought to reduce the effectiveness of a strike, the term is highly derogatory.
