Sexual Orientation Discrimination Laws in Colorado

Federal law protection against sexual orientation discrimination derives from Title VII of the Civil Rights Act of 1964, 42 U.S.C. § 2000e, which prohibits discrimination based on sex. In Bostock v. Clayton County, 140 S. Ct. 1731 (2020), the U.S. Supreme Court held that discrimination because of an individual's sexual orientation or transgender status constitutes unlawful sex discrimination under Title VII. Title VII covers all private employers with 15 or more employees, state and local governments, and labor unions.

Under the federal standard established in Bostock, employers cannot make decisions about employment based on whether an employee is gay, lesbian, or bisexual, or based on romantic or sexual attraction to persons of the same sex. This includes hiring, firing, compensation, job assignment, and harassment. The EEOC enforces Title VII and investigates charges of discrimination. Remedies under Title VII include back pay, front pay, compensatory and punitive damages (capped at varying amounts depending on employer size), attorney fees, and injunctive relief requiring reinstatement or promotion.

The federal baseline applies nationwide but does not preempt state laws that provide greater protection. Colorado has chosen to provide independent state-law protection that exceeds the federal floor.

Colorado Revised Statutes § 24-34-402 explicitly prohibits discrimination in employment based on sexual orientation, making Colorado one of the first states to provide this protection at the statutory level. This state law is substantially stronger than the pre-Bostock federal baseline because it creates independent state-law liability that does not depend on the sex discrimination theory now adopted by the Supreme Court in Bostock.

Under Colorado law, discrimination based on sexual orientation is a categorical protected class treated equivalently to race, color, creed, religion, sex, national origin, and disability. The statute applies to all employers with one or more employee working in Colorado, meaning the coverage threshold is far lower than Title VII's 15-employee threshold. This means that small employers in Colorado are covered by state law even if they fall below the federal employer size requirement.

Colorado's law prohibits discrimination in all aspects of employment: hiring, firing, compensation, job placement, promotion, job assignment, hours and shifts, benefits, conditions of work, and termination. It also prohibits retaliation against individuals who oppose discriminatory practices or participate in investigations. The Colorado Civil Rights Division, codified at § 24-34-306, investigates charges and can issue findings of probable cause, holding hearings, and issuing remedial orders.

Under Colorado law, remedies are comprehensive and include back pay, front pay, emotional distress damages, loss of enjoyment of life, attorney fees, and injunctive relief. Colorado law does not cap compensatory damages as Title VII does. Additionally, Colorado's law provides for attorney fees to a prevailing party, which incentivizes private enforcement. The state law standard does not require the plaintiff to prove they were replaced by someone outside the protected class; disparate treatment based on sexual orientation alone is sufficient.

Colorado law contains narrow exceptions. The primary exception involves religious organizations, which may be exempt from anti-discrimination requirements when hiring for roles integral to their religious mission, though this exemption is interpreted narrowly and does not extend to all employment decisions by religious employers. Colorado law does not protect contractors or independent contractors, only employees with an employer-employee relationship.

At-will employment remains the default rule in Colorado, but an employer cannot terminate an employee based on sexual orientation; doing so violates § 24-34-402 regardless of at-will status. The at-will doctrine cannot override statutory anti-discrimination protections. Private employers in Colorado may not claim a religious or conscience-based exception to the sexual orientation anti-discrimination rule unless they qualify as a bona fide religious organization under narrowly construed standards.

A key exception involves the statute of limitations: claims brought in court (rather than administrative complaints to the Colorado Civil Rights Division) may have different timelines depending on whether they are brought under state tort law or statutory provisions. However, the administrative filing deadline of 180 days is strict and failure to file within that window bars the administrative remedy. Employers may defend against discrimination claims by proving they would have made the same decision for a legitimate, non-discriminatory reason, but such affirmative defenses must be clearly substantiated and do not excuse discriminatory intent or mixed-motive decisions.

Step 1 — Document the discrimination. Keep detailed records of all incidents, including dates, times, locations, what was said or done, and names of witnesses. Save emails, text messages, performance reviews, disciplinary notices, pay stubs, and any communications showing discriminatory treatment or differences in how you are treated compared to similarly situated employees of different sexual orientations. Document your job duties, performance ratings, and compensation. Create a timeline with specific examples of exclusion from meetings, assignments being withheld, derogatory comments, or adverse employment decisions made around your sexual orientation.

Step 2 — File an internal complaint if your employer has a complaint procedure. Review your employee handbook for anti-discrimination policies and complaint channels. File a written complaint with Human Resources or the designated compliance officer, documenting the discrimination clearly and requesting a response within a specified timeframe (typically 10-20 business days). Keep a copy of your complaint and any responses. Internal complaints do not stop the statute of limitations clock, but they create an employer obligation to investigate and document that you reported the behavior. If your employer retaliates for making an internal complaint, that retaliation is itself illegal under Colorado law.

Step 3 — File with the Colorado Civil Rights Division. You must file a Charge of Discrimination within 180 days of the discriminatory act. Visit the Colorado Civil Rights Division website at https://dora.colorado.gov/civil-rights or call 303-894-2997. You can file online, by mail (Colorado Civil Rights Division, 1560 Broadway, Suite 1550, Denver, CO 80202), or in person. Your charge should include: (1) your name, address, and contact information; (2) the employer's name, address, and approximate size; (3) a description of the discriminatory act or practice; (4) the date(s) the discrimination occurred; (5) names and contact information of witnesses; (6) any documentation (emails, pay stubs, performance reviews). There is no filing fee. You do not need an attorney to file, but having one review your charge strengthens it.

Step 4 — Understand the investigation process. The Colorado Civil Rights Division will notify the employer of your charge and require them to submit a response, typically within 20-30 days. The Division will then investigate by reviewing documents, interviewing you, witnesses, and the employer's representatives, and examining employment records for patterns of discrimination. The investigation typically takes 30-90 days but can extend longer if complex issues are involved. After investigation, the Division issues a Determination Letter stating whether probable cause exists that discrimination occurred. If probable cause is found, the case moves to conciliation (settlement discussion); if conciliation fails, the case may go to a hearing before an administrative law judge or the Colorado Civil Rights Commission. You will receive updates throughout the process at the email and phone number you provided on your charge.

Step 5 — Consult an attorney. Contact a civil rights attorney as soon as you recognize a pattern of discrimination; you do not need to wait until after filing a charge. An employment discrimination attorney can review your documentation, assess the strength of your case, help you file your administrative charge correctly, and represent you during investigation and hearing. If you file a charge pro se (without an attorney) and the Division finds probable cause, you can still hire an attorney for the hearing phase. Colorado does not require you to pursue administrative remedies before filing a civil lawsuit, but pursuing the administrative route first is often strategic because it is free and creates an investigation record. An attorney can advise whether to simultaneously pursue state court litigation or wait for the Division's determination.
