It remains to be seen whether it will survive legal challenge.
We have a similar law in Ontario that I keep having to deal with on behalf of my employer, called the "Pay Equity Act" and it goes back twenty years. The law says that women's work (yes, "women's work", not women) must be paid
at least as much as men's work. They don't care about individual women being paid as much as men for the same job. They actually make you categorize jobs as "womens work" or "mens work". They also don't care if men's work doesn't get paid as much as women's work in an organization. It is completely one way.
The result is that you play with your definitions and monkey with the date until the government bureaucrats go away, and nobody, woman or man, actually gets helped in the end.
