When a predetermined period of time elapses in the input operation by the worker to the input unit (10), the worker is requested to input the subjective fatigue level of the worker. A fatigue level input step in which the subjective fatigue level of
A correlation storage step in which a correlation between the ratio of the number of cancellation inputs to the number of inputs and the fatigue level is stored in a correlation storage unit (32, 332);
The ratio of the number of cancel inputs to the number of inputs is calculated, and the fatigue of the operator is calculated from the ratio of the number of cancel inputs to the number of inputs by referring to the correlation storage unit (32, 332). A calculation step to estimate the degree;
A notification step of notifying the fatigue level of the worker estimated in the calculation step;
With
Work management program.
