How to calculate the piece-rate salary of employees who cut beds in garment factories?

General contracting can be implemented: for example, the personnel in the cutting room are calculated according to the total monthly cutting volume. If you cut 20 thousand pieces a month, each piece is 0. 5 yuan, * * * is 10000 yuan. If there are six people, then this 10000 yuan will be distributed by the general contractor, and then the distribution list will be submitted to the finance department. It should also be noted that if there are savings in materials, a certain proportion of savings awards will be given. On the other hand, if materials are used in excess, a certain percentage will be deducted. There is a premise that your company's monthly business volume should be accurate and know fairly well. It is also necessary to mobilize the enthusiasm of cutting personnel, and the salary should not be too high. That's what I did before, and it worked well.
