Colorado Equal Pay Act

Overview

The Colorado Equal Pay for Equal Work Act (EPEWA), codified as C.R.S. § 8-5-101 et seq., represents a landmark legislative effort in the United States to combat wage discrimination and promote pay equity. Signed into law by Colorado Governor Jared Polis on May 22, 2019, the Act became effective on January 1, 2021, introducing comprehensive provisions that significantly expanded upon existing federal and state equal pay protections. Its primary purpose is to eliminate gender-based wage disparities by ensuring that employees performing substantially similar work receive equal pay, regardless of sex or sex in combination with another protected status. The EPEWA is distinguished by its dual focus on proactive pay equity measures and robust pay transparency requirements, setting a new standard for workplace fairness in Colorado and serving as a model for other jurisdictions.

Historically, the fight for equal pay has been a protracted one, with the first equal pay bill introduced in Congress in 1944, eventually leading to the federal Equal Pay Act of 1963 and Title VII of the Civil Rights Act of 1964. Despite these earlier legislative efforts, significant wage gaps persisted, particularly for women and women of color. Reports in 2018 indicated that women in Colorado earned only 86 cents for every dollar men earned, with Latinas and Black women facing even larger disparities. Recognizing these persistent inequities and the limitations of existing laws, the Colorado General Assembly enacted the EPEWA to provide stronger mechanisms for achieving genuine pay equity. The Act was a key innovation, particularly in its pioneering pay transparency provisions, which were among the first of their kind in the nation, aiming to empower workers with critical information to make informed career decisions.

The EPEWA introduced several key innovations, including a ban on salary history inquiries, explicit protections for employees discussing wages, and stringent requirements for employers to disclose salary ranges and benefits in job postings and promotional opportunities. These measures aim to foster a more transparent and equitable labor market, empowering employees with information and holding employers accountable for fair compensation practices. The Act also established clear enforcement mechanisms through the Colorado Department of Labor and Employment (CDLE) and provided for significant penalties for non-compliance, alongside robust remedies for aggrieved employees. Subsequent amendments in 2024 and 2025 have further strengthened the Act, expanding pay transparency rules to include bonus and commission disclosures, increasing record-keeping requirements to ten years, and enhancing anti-retaliation protections, demonstrating Colorado's ongoing commitment to leading the nation in workplace fairness and economic justice.

Definitions

The Colorado Equal Pay for Equal Work Act establishes several critical definitions to delineate its scope and application. Central to the Act is the concept of "substantially similar work," which forms the basis for evaluating wage discrimination claims. This is defined not merely by job title, but by a comprehensive assessment of the composite of skill, effort (which may include consideration of shift work), and responsibility required for the performance of the work. This broad definition ensures that employers cannot circumvent the law by simply assigning different titles or minor, inconsequential differences to jobs that are essentially the same in terms of their demands and contributions to the organization. The focus on the actual duties and requirements of a position, rather than superficial distinctions, is crucial for effective equal pay enforcement and for preventing employers from creating artificial barriers to equal compensation.

The Act also defines "wage rate" broadly to encompass all forms of compensation. While the official text does not explicitly list every component, guidance from the Colorado Department of Labor and Employment (CDLE) and common legal interpretation suggest that "wage rate" includes not only base salary or hourly pay but also bonuses, commissions, benefits (such as health insurance, retirement contributions, and paid time off), and other forms of remuneration. This comprehensive view of compensation is vital to prevent employers from offering equal base pay but then creating disparities through other elements of the total compensation package, thereby undermining the spirit of the law. Furthermore, the Act addresses "promotional opportunities," requiring employers to announce these to all current employees. A "promotional opportunity" is generally understood as a vacancy in an existing or new position that could be considered a promotion for one or more employees in terms of compensation, benefits, status, duties, or access to further advancement, ensuring internal equity in career progression.

Key terms related to the Act's transparency provisions include "job opening" and "salary range." A "job opening" refers to any position for which an employer is seeking to hire, whether internally or externally, including temporary staff and remote positions that could potentially be performed in Colorado. The "salary range" refers to the hourly or salary compensation, or a range thereof, that the employer in good faith believes it may pay for the particular job. This range must be a genuine estimate and not open-ended phrases like "and up" or "up to," which would defeat the purpose of transparency. The Act also implicitly defines "protected status" by referencing Section 24-34-402 of Colorado law, which lists disability, race, creed, color, sex, sexual orientation, religion, age, national origin, or ancestry. While the EPEWA primarily focuses on sex-based discrimination, it also covers discrimination based on sex in combination with another protected status, thereby indirectly extending protections to these other categories when intertwined with sex discrimination, fostering an intersectional approach to pay equity.

Covered Employers

The Colorado Equal Pay for Equal Work Act applies broadly to nearly all employers operating within the state, encompassing both public and private entities. Specifically, the Act defines an "employer" as the state or any political subdivision, commission, department, institution, or school district thereof, and every other person employing a person in the state. This expansive definition means that there are no specific size thresholds for coverage; an employer with even a single employee in Colorado is subject to the Act's provisions. This broad applicability ensures that the protections and transparency requirements of the EPEWA extend across the vast majority of the Colorado workforce, regardless of the size or nature of the employing organization, from small businesses to large corporations and government agencies.

A significant and forward-thinking aspect of the EPEWA's coverage is its explicit inclusion of remote positions. The law applies to jobs that are physically located in Colorado, as well as those that could potentially be performed in Colorado, including fully remote roles. This provision is particularly relevant in the modern work landscape, preventing employers from circumventing the Act's transparency requirements by designating positions as remote and attempting to exclude Colorado-based applicants or employees from the benefits of the law. The Colorado Department of Labor and Employment (CDLE) has issued guidance clarifying that employers cannot avoid the Act's posting requirements by stating that a job position can be performed "anywhere but Colorado." This ensures that individuals residing in Colorado, even if working remotely for an out-of-state employer, are afforded the same protections and access to pay transparency, promoting fairness in a geographically dispersed workforce.

While the Act's coverage is extensive, there are limited exceptions or nuances to consider, though these are generally narrow and do not diminish the overall universal application. For instance, certain temporary roles or frequently posted roles may have modified requirements regarding promotional opportunity announcements, such as positions that are not considered
