Working less is not the same as waiving your salary. It just means you aleady have enough money for a good quality of life. An altruistic person that is not greedy would reject their salary, knowning that it will worsen their quality of life. Nobody would do that because everyone is greedy for a better life of their own.
A huge portion of the Netherlands works part time by choice. So, yes, many people voluntarily waive parts of their salary.
