How to calculate the middle shift salary of hotel housekeeping staff in the specific piece-rate scheme

The middle class can't get piecework pay, because the workload of the middle class can't be compared with that of the morning class. If you work by piece, the wages of middle-class employees will be very low, which will affect the enthusiasm of employees. Therefore, the middle class should adopt the fixed wage method and calculate according to the fixed working hours. And the middle shift and the early shift should be adjusted every month. The middle shift should not stay in the middle shift, and the early shift should stay in the early shift.
