The EU Pay Transparency Directive came into effect in June 2023, and the member states have three years to incorporate it into domestic law.

Key points:
1. Pay ranges must always be disclosed in job ads.
2. Companies cannot ask about previous or current pay.
3. Companies cannot prohibit employees from disclosing their pay details.
4. Employees can request information about their pay level, and average pay levels broken down by gender and category of workers doing the same or equal work.

@redhatworkers that's awesome! Would love to see something like that in the USA!

Some states do have pay transparency laws and bans on pay history, California is the latest one to adopt such legislation in 2023: https://www.shrm.org/resourcesandtools/hr-topics/talent-acquisition/pages/state-pay-equity-laws.aspx (This website should not be treated as the source of truth, but it links to the respective bills in each state.)

Also, the right to discuss and disclose your salary is protected by the National Labor Relations Act: https://www.nlrb.gov/about-nlrb/rights-we-protect/your-rights/your-rights-to-discuss-wages
