Sex discrimination involves treating someone (a job applicant or employee) unfavorably because of that person's sex. Sex discrimination is a form of employment discrimination that violates federal law—including Title VII of the Civil Rights Act of 1964 (42 U.S.C. §2000e).

In addition to these federal laws, states also have laws against sex discrimination in employment. These state laws are generally located in a state’s statutes—often in the labor code or employment-related statutes.

Discrimination against an individual because of gender identity—including transgender status or sexual orientation—is discrimination because of sex in violation of Title VII.

The law forbids discrimination when it comes to any aspect of employment, including hiring, firing, pay, job assignments, promotions, layoff, training, fringe benefits, and any other term or condition of employment.

For the regulations related to sex discrimination, see the Code of Federal Regulations, beginning with 29 CFR 1604.1.

In Wyoming, sex discrimination in employment is prohibited under federal law, specifically Title VII of the Civil Rights Act of 1964, which makes it illegal to discriminate against someone on the basis of sex. This includes discrimination in hiring, firing, pay, job assignments, promotions, layoffs, training, benefits, and other terms or conditions of employment. Additionally, discrimination on the basis of gender identity, including transgender status, or sexual orientation is also recognized as a form of sex discrimination under Title VII. While Wyoming does not have a specific state statute that addresses sex discrimination in employment beyond these federal protections, employers in the state must comply with federal regulations as outlined in the Code of Federal Regulations, starting with 29 CFR 1604.1. It is important for employers and employees to understand these regulations to ensure compliance and to protect the rights of all individuals in the workplace.
