Legislation in Washington state known as the strippers’ bill of rights, which advocates say includes the most comprehensive statewide protections in the nation, was signed into law on Monday.

The new law requires training for employees in establishments to prevent sexual harassment, identify and report human trafficking, de-escalate conflict and provide first aid. It also mandates security workers on site, keypad codes on dressing rooms and panic buttons in places where entertainers may be alone with customers.

Most dancers in the state are independent contractors who are paid by customers and then must pay club fees every shift. The new law limits the fees owners can charge, capping them at $150 or 30% of the amount dancers make during their shift — whichever is less. It also prohibits late fees and other charges related to unpaid balances.

Only one other state has added worker protections for adult entertainers, according to the National Conference of State Legislatures. In 2019, Illinois started requiring that adult entertainment establishments, along with other businesses, have a written sexual harassment policy.

There have also been other efforts — including at a bar in Los Angeles and a strip club in Portland, Oregon, where dancers voted to unionize. And, the Nevada Supreme Court in 2014 ruled that dancers at one Las Vegas club are employees, and are entitled to minimum wage and other protections.
