Wisconsin Fair Employment Act — employer coverage threshold
The Wisconsin Fair Employment Act (WFEA) applies to employers with at least one employee. This coverage is broader than most federal anti-discrimination statutes — Title VII requires 15 employees, the ADA requires 15, and the ADEA requires 20. Under Wis. Stat. § 111.32(6)(a), "employer" means the state and each agency of the state and any other person engaging in any activity, enterprise, or business employing at least one individual. The statute exempts only social clubs or fraternal societies under Wis. Stat. Ch. 188 with respect to jobs advertised solely within the membership.

Wisconsin Fair Employment Act — protected classes
The Wisconsin Fair Employment Act (WFEA) prohibits employment discrimination on the basis of age, race, creed, color, disability, marital status, sex, national origin, ancestry, sexual orientation, arrest record, conviction record, military service, use or nonuse of lawful products off the employer's premises during nonworking hours, and declining to attend a meeting or to participate in any communication about religious matters or political matters. This list is broader than federal anti-discrimination law — notably including arrest record, conviction record, marital status, and protections for declining to attend meetings about religious or political matters.
