Defines "adverse action" to include refusal to hire or promote, discharge, demotion, harassment, discrimination in compensation or employment terms, or any other employment decision that adversely affects an employee.

Applies the prohibition to all employers transacting business in Colorado, including state and local government entities.

Takes effect 12:01 a.m. the day following the 90-day period after final adjournment of the general assembly, unless subject to a referendum petition requiring voter approval at the November 2022 general election.
