Yes, Colorado is a right-to-work state under Colorado Revised Statutes section 8-3-101. This means you cannot be required to join a union, pay union dues, or pay fair-share fees as a condition of employment. The law applies to all private sector employers in Colorado with no employee count threshold. You have the right to work without union membership, and employers cannot discriminate against you for choosing not to join a union.

Federal Law: The Baseline
Federal law establishes a framework for union organization and collective bargaining primarily under the National Labor Relations Act (NLRA), 29 U.S.C. section 151 et seq. The NLRA allows private sector employees to organize and collectively bargain through unions. However, Section 14(b) of the TAFT-Hartley Act, 29 U.S.C. section 164(b), permits individual states to pass right-to-work laws that restrict union security agreements. Federal law does not mandate right-to-work status; it authorizes states to adopt it.
Under federal law, if a state does not have a right-to-work statute, unions can negotiate union security agreements requiring employees to join the union or pay fair-share fees (agency fees) as a condition of employment. The NLRB enforces federal labor law. Without state right-to-work protections, employees in non-right-to-work states can be terminated for refusing to pay union fees, even if they object on religious or philosophical grounds.
Federally, the only protection is that an employee cannot be forced to pay for union political activities; fees must be limited to representational activities. The Supreme Court's 2018 decision in Janus v. AFSCME altered this somewhat for public sector employees, but private sector law remains governed by the NLRA framework and state right-to-work laws.
Colorado Law: What's Different
Colorado Revised Statutes section 8-3-101 establishes Colorado as a right-to-work state, making it stronger than the federal baseline for employee choice. The statute provides that no person shall be denied employment or continued employment based on membership or non-membership in any labor organization. This applies to all private sector employers operating in Colorado with no employee count threshold.
Colorado's law differs from federal law in several critical ways. While the NLRA permits union security agreements in non-right-to-work states, Colorado prohibits them entirely under state law. Section 8-3-102 specifically protects an employee's right to refrain from joining a union or engaging in union activities. An employer cannot condition hiring, firing, promotion, or any employment benefit on union membership or payment of union dues or fees.
Uniquely, Colorado law also protects employees from discrimination based on union non-membership. An employer or union cannot discriminate against, threaten, coerce, or retaliate against an employee who exercises their right not to join a union. This protection exceeds federal standards, which focus primarily on union organizing activity rather than protection for union non-membership.
Colorado Revised Statutes section 8-3-103 provides remedies including actual damages (lost wages, emotional distress), exemplary damages if the violation is willful, court costs, and reasonable attorney fees. An employee can sue directly under state law in Colorado state court. Unlike the NLRA, which requires NLRB involvement, Colorado law gives employees a private right of action. Unions retain the right to organize and represent workers; the law does not restrict union activity, only the ability to mandate membership or fees as employment conditions.
Key Numbers & Thresholds
Colorado right-to-work law applies to all private sector employers with no minimum employee count threshold. There is no filing deadline for right-to-work complaints; Colorado Revised Statutes section 8-3-103 allows civil actions under standard statute of limitations for contract and tort claims (typically 2-6 years depending on claim type). Remedies include actual damages, exemplary damages, court costs, and reasonable attorney fees. No administrative filing is required before pursuing a civil lawsuit; employees can file directly in Colorado state court.
Exceptions & Special Cases
Colorado's right-to-work law contains important exceptions and limitations. First, the law applies only to private sector employers. Public sector employees in Colorado (federal, state, and local government) are not covered by the state right-to-work statute; federal law applies to them under the First Amendment and NLRA. Government employees have different protections and restrictions on union security agreements.
Second, the law does not prohibit voluntary union membership or voluntary payment of union dues. An employee who chooses to join a union and pay fees does so by choice; the law protects only those who choose not to participate. Unions can still organize, recruit members, and negotiate contracts; they simply cannot make membership or fee payment a condition of employment.
Third, independent contractors and certain occupational categories may fall outside traditional employment relationships. Someone who is properly classified as an independent contractor rather than an employee is not protected by the right-to-work statute because they are not an "employee" as defined under Colorado law.
Fourth, the law does not override legitimate union representation. A union certified or recognized as the exclusive bargaining representative can still negotiate on behalf of all employees in the unit, including non-members. However, the union cannot use membership or fee payment as a lever for that representation.
Finally, Colorado law does not protect employees from lawful union activity such as strikes, picketing, or boycotts. The right-to-work statute protects individual employee choice but does not restrict union organizing or collective action. An employee cannot be retaliated against for refusing union membership, but they may face consequences for participating in lawful strikes or union activities.
What to Do If Your Rights Are Violated
Step 1: Document the violation immediately. Keep written records of all communications related to union membership or fee demands, including emails, letters, text messages, and notes on verbal conversations. Record dates, times, who said what, and any witnesses. Collect pay stubs, employment contracts, and any documents showing union fee deductions from your paycheck. Take screenshots of internal communications or company policies requiring union membership. Create a timeline showing when the demand was made and any adverse employment action (denial of hire, termination, demotion, reduced hours) that followed your refusal.
Step 2: File an internal complaint if your employer has a complaint process. Notify HR or management in writing (email is acceptable) that you are asserting your right under Colorado Revised Statutes section 8-3-101 not to join a union and that you believe the company is violating that right. Keep a copy of this complaint. This creates a paper trail and may prompt internal investigation. However, do not wait on internal resolution; Colorado law does not require exhaustion of internal remedies before filing a lawsuit. Your employer is unlikely to have a formal right-to-work complaint process, so this step may be limited in practice.
Step 3: Consult an employment attorney licensed in Colorado immediately. Right-to-work violations are civil claims, not administrative complaints to a government agency. You do not file with the Colorado Department of Labor or any administrative body. Instead, you have a direct private right of action to sue in Colorado state court (District Court). An attorney can evaluate whether your case is strong, negotiate with your employer or union, or file a lawsuit. Most Colorado employment attorneys work on contingency for right-to-work cases, meaning you pay no upfront fee.
Step 4: Your attorney will file a civil complaint in the appropriate Colorado District Court (usually the county where you work or reside). The lawsuit names your employer and/or the union as defendants. Discovery follows, meaning both sides exchange documents and testimony. This typically takes 6-12 months. You may be able to seek a preliminary injunction to stop ongoing violations during the case. The case may settle or proceed to trial. Under Colorado Revised Statutes section 8-3-103, if you prevail, you recover actual damages (lost wages, emotional distress), exemplary damages if the violation was willful (up to double actual damages), court costs, and reasonable attorney fees.
Step 5: Consider damages and strategy with your attorney. Right-to-work cases focus on whether the employer or union made union membership or fee payment a condition of employment or retaliated against you for refusing. Prove the violation by showing a causal link between your refusal and an adverse employment action (firing, demotion, denial of hire). If you were terminated, damages include back pay, benefits, and front pay if reinstatement is not feasible. Willful violations (where the employer knew of the law and violated it anyway) result in exemplary damages. Your attorney will advise whether settlement or trial is more advantageous.

Frequently Asked Questions
Does Colorado right-to-work law apply to government employees?
No. Colorado Revised Statutes section 8-3-101 applies only to private sector employees. Public sector employees (federal, state, and local government workers) are not covered by the state right-to-work statute. Federal law governs them under the National Labor Relations Act and the First Amendment. Public sector employees have different rules regarding union security agreements. Some federal employees are covered by the Federal Employees Health Benefits Act and other federal statutes. If you are a government employee, consult an attorney familiar with public sector labor law rather than Colorado state right-to-work law.
Can a union legally require me to pay fair-share fees in Colorado even if I don't join?
No. Colorado Revised Statutes section 8-3-101 prohibits unions from requiring you to pay fair-share fees, agency fees, or any fees as a condition of employment. This applies regardless of whether the union is negotiating your contract or representing you in a bargaining unit. You cannot be required to pay any amount to a union as a condition of working, even if the union argument is that non-members benefit from union negotiation. If a union or employer attempts to deduct union fees from your paycheck without your voluntary written authorization, that violates Colorado law. You can recover those deducted funds plus damages through a civil lawsuit.
What counts as retaliation for refusing to join a union in Colorado?
Under Colorado Revised Statutes section 8-3-102, retaliation includes any adverse employment action taken because you refused to join a union or pay union fees. Examples include termination, demotion, reduction in pay or hours, denial of promotion, exclusion from desirable assignments, negative performance reviews unrelated to actual performance, or harassment by coworkers (if the employer knew and tolerated it). The key legal test is causation: was the adverse action taken because of your refusal to unionize, or would it have happened anyway for legitimate reasons? If you were fired shortly after refusing union membership and your employment record was otherwise clean, that timing strongly suggests retaliation. Document everything and consult an attorney if you experience any negative employment action after asserting your right-to-work.
Can I lose my job if I refuse to vote for union representation or a union contract?
No. Colorado law protects not only non-membership but also your right to refrain from union activities. This includes the right to refuse to vote for union representation, union elections, or contract ratification votes. An employer or union cannot terminate, discipline, or retaliate against you for how you vote in union elections or contract votes, or for refusing to participate in voting. However, if you participate in a lawful strike authorized by a union, your employer has different rights; this protection does not guarantee your job during a strike. The right-to-work protection covers your choice whether to join or participate, not protection from economic consequences of authorized strikes in which you choose to participate.
How long do I have to file a lawsuit for a right-to-work violation in Colorado?
There is no special administrative deadline for Colorado right-to-work claims because they are civil lawsuits, not agency complaints. However, you are subject to the general statute of limitations for contract and tort claims in Colorado, which is typically two to six years depending on the type of claim (breach of contract, tort, discrimination). The clock generally starts when the violation occurs or when you discover it. If you are terminated, damages include back pay and other losses from the date of termination forward. Do not delay in consulting an attorney if you believe you have been harmed; the longer you wait, the weaker your case becomes due to fading evidence and witness memories. Most Colorado employment attorneys offer free initial consultations.
