Prohibits employers from taking adverse employment actions against workers who express the view that sex is binary/biological or who request or use single‑sex spaces (for example, bathrooms or changing rooms). Employers would not be allowed to defend such actions by saying they were job‑related or necessary for business. The bill also indicates a related change to the prohibition on retaliation under Title VII, but the specific amendment text for that change was not provided in the available excerpt, leaving that portion unclear.
