In the U.S., there are now 13 cities and states that require employers to share salary information, covering about 1 in 4 workers, according to Payscale, a software firm focusing on salary comparison.In a comment to CNBC, a Meta spokesperson said, "To ensure fairness and eliminate bias in our compensation systems, we regularly conduct pay equity analysis, and our latest analysis confirms that we continue to have pay equity across genders globally and by race in the US for people in similar jobs."The second part requires companies with more than 100 employees to submit a pay data report to the state of California with detailed salary information broken down by race, sex and job category."That means that their earning power and how they're able to contribute to this economy in California, whether it's through a sales market, a housing market, through investment, is limited, because they are not being paid equitably."Loopholes The new law doesn't require employers to post total compensation, meaning that companies can leave out information about stock grants and bonuses, offering an incomplete picture for some highly paid jobs."
