Wave-like fluctuation of the time attending execution of monotonous operations reveal the presence of a certain cadence in the performance of work . This cadence is unstable and varies within a definite range in its frequency and amplitude, so that the periodicity is fixed statistically against the background of chance fluctuations. The lengths of the oscillation periods are similar to each other with different types of work, as concerns the number of operations making up a period, and this is irrespective of the duration of the operations. The rigid pace of the conveyor produces a synchronizing influence on the nature of time fluctuation in performing the operations. Such periodic fluctuations and their changes under the effect of a forced pace of technological processes should be considered in planning, organization and hygienic evaluation of the work.
