How to establish a reasonable salary system for hotel room attendants?

Many hotels use a combination of fixed salary and piece-rate commission. For example, the number of rooms in a month is the limit. If you don't do enough (there are not so many rooms to do in the off-season), you will be paid according to a fixed basic salary. This is a guarantee. Anyway, at least you can get so much money. Then, if you exceed the quota, you will get a commission according to the number of guests and the number of check-outs, which means you will get more work.
