This document traces the shift in workplace ethics from the craft ethic of the late 19th century to the entrepreneurial ethic brought about by scientific management in the early 20th century. Under the craft ethic, craft workers had autonomy over their work processes while management determined production goals. Frederick Taylor then introduced scientific management, developing time studies, job analysis, and standardized tasks to maximize efficiency. While this increased productivity, it reduced worker autonomy and was met with resistance from unions who felt it dehumanized labor.
