Ok, kids - we're up to 10 states and 8 municipalities that have outlawed/banned asking candidates questions about pay history.
That's a lot. Kind of sneaks up on you.
The laws are aimed at ending the cycle of pay discrimination and some go further than merely banning pay history questions. A few also prohibit an employer from relying on an applicant's pay history to set compensation if discovered or volunteered; others prohibit an employer from taking disciplinary action against employees who discuss pay with coworkers.
The best running updated list is found here - at HRdive. Go check it out.
