Mass-production techniques and technology called for setting up huge factories with large work force. It created a lot of jobs but due to the division of labor, the skill requirements for a particular job were quite monotonous. Skilled workers were replaced by machines and unskilled machine operators that could perform a single task instead of an array of tasks.
