What Is Considered Unlawful Termination in Colorado?

Wrongful termination in Colorado is a firing that violates a specific law or contract, even though Colorado is an at-will state. At-will means your employer can fire you for almost any reason, but federal and Colorado statutes carve out a long list of reasons that are off-limits: discrimination, retaliation for exercising a legal right, breach of an employment contract, and punishment for lawful activity you do on your own time, among others. If your termination fits one of those categories, you may be entitled to back pay, reinstatement, emotional distress damages, and attorney’s fees, but only if you file with the right agency within deadlines that can be as short as 10 days.

When a Colorado Firing Crosses the Line

Under Colorado’s at-will rule, either side can end the employment relationship at any time for any reason that isn’t illegal.1Colorado Department of Labor and Employment. INFO #5A Retaliation Protections The question is always what counts as illegal. In Colorado, a firing is unlawful if it falls into one of these categories:

  • Discrimination based on a protected characteristic.
  • Retaliation for reporting illegal conduct, filing a workers’ compensation claim, taking protected leave, or raising safety concerns.
  • Punishment for refusing to do something illegal, or for doing something the law protects (jury duty, voting, cooperating with investigators).
  • Breach of a written, oral, or implied employment contract.
  • Termination for lawful off-duty conduct, with narrow exceptions.
  • A mass layoff that skipped the federally required 60-day notice.

One category Colorado does not recognize: a general duty of good faith and fair dealing in at-will employment.2Justia. Colorado Revised Statutes Section 4-1-304 – Obligation of Good Faith If your employer fires you a week before your commission vests, that alone is not wrongful termination. The unpaid commission itself may still be recoverable as a wage claim, but the firing is not actionable on good-faith grounds.

Discrimination-Based Firings

The Colorado Anti-Discrimination Act (CADA) prohibits firing someone because of disability, race, color, sex, sexual orientation, gender identity, gender expression, religion, age, national origin, ancestry, marital status, creed, or pregnancy-related conditions.3Colorado Civil Rights Division. Colorado Law Prohibits Discrimination in Employment CADA applies to employers of all sizes. That matters because the parallel federal laws (Title VII, the ADA, the ADEA) generally only cover employers with 15 or more employees, and 20 for age claims. If you work for a small business, CADA is often your only path.

Direct proof of discrimination is rare. What courts actually look at is circumstantial: workplace policies applied unevenly, biased remarks by supervisors, write-ups that appear out of nowhere right before termination, and shifting explanations for why you were let go. The employer gets to offer a legitimate business reason, and then you get the chance to show that reason is a cover story.4United States Department of Justice. Civil Rights Division – Section VI – Proving Discrimination – Intentional Discrimination

Pregnancy and Nursing

Pregnant workers and new parents sit under layered protections. CADA covers pregnancy-related conditions, and the federal Pregnant Workers Fairness Act requires reasonable accommodations for limitations related to pregnancy, childbirth, or recovery: modified schedules, extra breaks, temporary reassignment, telework, or light duty.5eCFR. Part 1636 Pregnant Workers Fairness Act An employer cannot fire you for requesting an accommodation, force you onto leave when an accommodation would work, or refuse to hire you because you might need accommodations down the road. The PUMP for Nursing Mothers Act separately protects employees who need time and private space to express breast milk and bars retaliation for requesting or using pumping breaks.6U.S. Equal Employment Opportunity Commission. Time and Place to Pump at Work – Your Rights

Retaliation and Whistleblower Firings

Retaliation drives a large share of wrongful termination cases. Colorado and federal law both prohibit firing, demoting, cutting pay, or otherwise punishing employees who report unlawful conduct or exercise workplace rights.1Colorado Department of Labor and Employment. INFO #5A Retaliation Protections Specific protections include:

  • Public policy: Colorado courts protect employees fired for serving on juries, filing workers’ compensation claims, or refusing to participate in illegal activity.7National Conference of State Legislatures. At-Will Employment – Overview
  • Public Health Emergency Whistleblower (PHEW) Act: Protects any private-sector worker, including independent contractors, who raises concerns about workplace health or safety violations or significant threats to health or safety. Your belief about the violation only has to be reasonable and in good faith, not correct.8Legal Information Institute (LII) / Cornell Law School. 7 CCR 1103-11-5 – Protected Activity Under PHEW
  • State Employee Protection Act: Covers state government employees who disclose agency actions not in the public interest. The complaint window is 10 days from the retaliatory action, filed with the State Personnel Board.9State Personnel Board. Whistleblower Claims
  • FMLA: Employers cannot interfere with your right to take up to 12 weeks of leave for a serious health condition, a new child, or a sick family member, and cannot fire you for using it.10U.S. Department of Labor. Unlawful Retaliation Under the Laws Enforced by WHD

Timing is powerful evidence in these cases. A termination that lands shortly after a protected report or leave request is exactly what investigators scrutinize.11U.S. Equal Employment Opportunity Commission. Enforcement Guidance on Retaliation and Related Issues

Separately, federal law also protects your right to talk with coworkers about wages, benefits, and working conditions, even without a union. Discussing pay, circulating a petition, bringing group complaints to management, or jointly refusing unsafe work all count as protected concerted activity under the National Labor Relations Act, and your employer cannot fire you for it.12National Labor Relations Board. Concerted Activity Social media posts tied to group concerns are covered too, though pure personal venting and knowingly false statements are not.13National Labor Relations Board. Social Media

Firings for Lawful Off-Duty Conduct

This is a protection most Colorado workers don’t know they have. Under C.R.S. ยง 24-34-402.5, your employer generally cannot fire you for any lawful activity you engage in off the employer’s premises during nonworking hours.14Justia. Colorado Revised Statutes Title 24 Article 34 Part 4 Section 24-34-402.5 That covers legal recreational activities, political speech, social media posts made on your own time, and other lawful personal conduct outside work.

Two exceptions apply. An employer can restrict off-duty conduct that relates to a genuine occupational requirement tied to your specific role, or where avoiding the conduct is necessary to prevent a conflict of interest with your job responsibilities. A blanket policy applied to everyone usually will not meet that bar.

Firings That Violate a Contract or Handbook Promise

If you have an employment contract, written or oral, your employer has to honor its terms. Skipping a required notice period, bypassing a progressive discipline process the contract spells out, or terminating you before the contract’s end date without the stated grounds is a breach.

Even without a formal contract, an employer’s own policies and statements can create an enforceable promise. If an employee handbook lays out a progressive discipline process, or a manager gave repeated assurances about job security, a court may treat those as binding. Colorado employers know this and typically bury a disclaimer in the handbook saying the policies create no contract. Those disclaimers only work if they are clear and conspicuous. A buried line in a hundred-page manual will not necessarily override years of consistent practice.

Contract claims go straight to court. The statute of limitations is three years for written contracts and two years for oral ones, measured from the date of the breach.15Justia. Colorado Revised Statutes Section 4-2-725 – Statute of Limitations in Contracts for Sale

Mass Layoffs Without Notice

If you lost your job as part of a large reduction rather than an individual termination, the federal Worker Adjustment and Retraining Notification (WARN) Act may apply. Employers with 100 or more full-time employees have to give at least 60 calendar days of advance written notice before a plant closing or mass layoff.16eCFR. 20 CFR 639.3 – Definitions WARN is triggered by:

  • Plant closing: A shutdown at a single site causing job losses for 50 or more full-time employees in a 30-day period.
  • Mass layoff: A reduction affecting at least 50 full-time employees who make up at least 33% of the site’s workforce, or any layoff affecting 500 or more full-time employees regardless of percentage.

An employer that skips the notice owes each affected employee up to 60 days of back pay and benefits. Workers or their union sue in federal court directly; the Department of Labor does not enforce WARN. Courts can also award reasonable attorney’s fees.17U.S. Department of Labor.

Where to File and How Long You Have

Getting the right agency and meeting the right deadline is where valid claims most often fall apart. The right venue depends on the type of claim.

Discrimination and Retaliation

File with the Colorado Civil Rights Division (CCRD) or the Equal Employment Opportunity Commission (EEOC). Colorado has a work-sharing agreement with the EEOC, so filing with one agency generally cross-files with the other.11U.S. Equal Employment Opportunity Commission. Enforcement Guidance on Retaliation and Related Issues The deadline is typically 300 days from the adverse action, though some claims carry shorter windows. After the agency investigates, it will attempt resolution or issue a Notice of Right to Sue. Once you get that letter, you have exactly 90 days to file a lawsuit. Miss it and the claim is gone.18U.S. Equal Employment Opportunity Commission. Filing a Lawsuit

Safety and Whistleblower Claims

Workplace safety retaliation complaints go to OSHA. Filing deadlines range from 30 to 180 days depending on the specific statute involved.19Occupational Safety and Health Administration. File a Complaint State employee whistleblower claims go to the State Personnel Board within 10 days.9State Personnel Board. Whistleblower Claims

Contract Claims

No agency step. File a lawsuit directly in state court within three years (written contract) or two years (oral).

What You Can Recover (and What the IRS Takes)

The remedies available depend on the type of claim, but the usual categories include:

  • Back pay: Wages, commissions, tips, and benefits lost from termination through resolution.
  • Front pay: Future wage losses when reinstatement is not practical.
  • Reinstatement: Returning you to your former position or an equivalent role.
  • Emotional distress damages: Available under statutes allowing actual damages, though for some claims (such as health and safety whistleblowing) only a court can award them, not the Division of Labor.
  • Punitive damages: Available in cases of egregious misconduct.
  • Attorney’s fees: Often awarded to the prevailing employee.
20Colorado Division of Labor Standards and Statistics. INFO #5C Complaints, Investigations, and Remedies as to Retaliation or Interference

Then the IRS gets involved. Back pay and lost wages are taxable income subject to federal income tax and employment taxes. Emotional distress damages from employment discrimination claims are also taxable, because they do not stem from a physical injury. Punitive damages are always taxable.21Internal Revenue Service. Tax Implications of Settlements and Judgments The one category that escapes taxation is damages received on account of physical injuries or physical sickness. Pure employment discrimination awards, even those labeled emotional distress, do not qualify for the exclusion. How a settlement allocates damages across these categories can mean thousands of dollars in tax difference, which is one reason to involve a lawyer before accepting a lump-sum offer.

Protecting Your Claim Now

After a wrongful termination, you have a legal duty to mitigate your damages by making a reasonable effort to find comparable replacement work. Courts will reduce your back pay by what you earned, or reasonably could have earned, during the period between your firing and resolution of the case.22United States Court of Appeals Tenth Circuit. NLRB v Community Health Services Inc The replacement work has to be substantially equivalent, so you do not have to take anything. But you do have to be actively searching, and you need records: applications, interviews, networking contacts, rejections.

Preserve everything else too. Save emails, performance reviews, text messages with supervisors, the employee handbook version in effect when you were fired, and anything documenting the timeline. Evidence disappears quickly. Witnesses forget, email accounts get deactivated, and company records get “updated.”

Most employment attorneys offer free initial consultations and many work on contingency, typically 25% to 40% of the recovery, so there is no upfront cost to find out whether your facts support a claim. Given that some deadlines run as short as 10 days, the single most important move after an unlawful termination is to act fast.
