But Taylor raised the concept of control to an entirely new plane when he asserted as an absolute necessity for adequate management the dictation to the worker of the precise manner in which work is to be performed.  That management had the right to “control” labor was generally assumed before Taylor, but in practice this right usually meant only the general setting of the tasks, with little direct interference in the worker’s mode of performing them.  Taylor’s contribution was to overturn this practice and replace it by the opposite (62).
