Although it is accepted that the scientific management enables the management to put resources to its best possible use and manner, yet it has not been spared of severe criticism.
Unemployment - Workers feel that management reduces employment opportunities from them through replacement of men by machines and by increasing human productivity less workers are needed to do work leading to chucking out from their jobs.
Exploitation - Workers feel they are exploited as they are not given due share in increasing profits which is due to their increased productivity. Wages do not rise in proportion as rise in production. Wage payment creates uncertainty & insecurity (beyond a standard output, there is no increase in wage rate).
Monotony - Due to excessive specialization the workers are not able to take initiative on their own. Their status is reduced to being mere cogs in wheel. Jobs become dull. Workers loose interest in jobs and derive little pleasure from work.
Weakening of Trade Union - To everything is fixed & predetermined by management. So it leaves no room for trade unions to bargain as everything is standardized, standard output, standard working conditions, standard time etc. This further weakens trade unions, creates a rift between efficient & in efficient workers according to their wages.
Over speeding - the scientific management lays standard output, time so they have to rush up and finish the work in time. These have adverse effect on health of workers. The workers speed up to that standard output, so scientific management drives the workers to rush towards output and finish work in standard time.
Expensive - Scientific management is a costly system and a huge investment is required in establishment of planning dept., standardization, work study, training of workers. It may be beyond reach of small firms. Heavy food investment leads to increase in overhead costs.
Time Consuming - Scientific management requires mental revision and complete reorganizing of organization. A lot of time is required for work, study, standardization & specialization. During this overhauling of organization, the work suffers.
