There is a discussion in the repo [1] (in Chinese) suggesting designing a new clause to existing software licenses for labor protection. For example, (from one of the post)

> the source code is not permitted to use at 996ICU style work environment.

The idea is that, if popular open source projects adopt this clause in their licenses, the work environment in China and maybe other countries will be improved.

I guess it can be more specific about "996ICU" or specify average weekly work hours limit etc. But the question is, how feasible will such license clause be? Will there be any insurmountable limitation that makes it useless in practice?
