Wrongful Termination in Denver: Laws, Deadlines, and Filing

A wrongful termination in Denver is a firing that violates a specific state or federal law, breaches an employment contract, or punishes you for exercising a legal right. Colorado is an at-will state, so most firings are legal even when they feel deeply unfair. What matters is whether your employer’s reason crossed one of the lines drawn by Colorado statutes, Denver ordinances, or federal law, and whether you act before the filing deadlines close.

When a Firing Is Actually Wrongful in Colorado

Under at-will employment, either side can end the relationship at any time, for any reason or no reason, with no advance notice.¹ An employer can fire you for a reason that is petty, inconsistent, or simply wrong about the facts. None of that makes the firing illegal.

The at-will rule breaks down in three situations:

Discrimination based on a protected characteristic.
Retaliation or a firing that violates public policy — for refusing to break the law, reporting illegal activity, filing a workers’ compensation claim, or exercising another legal right.
Breach of a written employment agreement, a collective bargaining agreement, or in some cases an implied contract created by the employer’s own handbook or policies.

The implied contract exception catches employers off guard more often than the others. When a handbook describes a progressive discipline process or says employees will only be fired “for cause,” a Colorado court can treat that language as an enforceable promise, even without a signed contract. A boilerplate at-will disclaimer buried elsewhere in the same handbook does not always undo it.

Who Is Protected Against Discriminatory Firing

The Colorado Anti-Discrimination Act, at C.R.S. § 24-34-402, makes it illegal to fire someone because of disability, race, creed, color, sex, sexual orientation, gender identity, gender expression, marital status, religion, age, national origin, or ancestry.² Gender identity and marital status are explicitly listed under state law, regardless of federal coverage.

One important feature of CADA: it applies to employers of every size. Title VII and the Americans with Disabilities Act only reach employers with 15 or more employees, and the Age Discrimination in Employment Act requires at least 20. If you work for a small Denver business under those thresholds, federal law may not help, but CADA still does.

Denver’s Additional Categories

Denver’s own anti-discrimination ordinance adds employment protections beyond CADA, including citizenship, immigration status, military status, source of income, and protected hairstyles.³ If your situation does not fit a CADA category, check whether the city ordinance covers it.

Retaliation and Refusing Illegal Orders

The Colorado Supreme Court recognized a public policy exception to at-will employment in Martin Marietta Corp. v. Lorenz. An employer cannot fire a worker for refusing to perform an illegal act, as long as the employer knew or should have known the refusal rested on a reasonable belief that the act was unlawful.⁴ A supervisor who tells you to falsify safety records or lie to a government auditor, and then fires you when you refuse, has handed you a textbook wrongful discharge claim.

Retaliation for filing a workers’ compensation claim is also illegal in Colorado, and the same principle protects employees who report workplace safety violations. OSHA enforces whistleblower protections covering more than 20 federal statutes, including reports of safety hazards, environmental violations, and financial fraud. The deadline for an OSHA retaliation complaint is just 30 days from the adverse action, which is far shorter than any discrimination deadline.

Firings for Lawful Off-Duty Conduct

Colorado offers a protection most states do not. Under C.R.S. § 24-34-402.5, your employer cannot fire you for engaging in any lawful activity outside of work during non-working hours.⁵ This covers political activity, lifestyle choices, and legal recreational use. The exceptions are narrow: the employer has to show the restriction relates to a genuine job requirement or avoids a real conflict of interest. A trucking company can bar drivers from drinking within hours of a shift. A retail store cannot fire a cashier over their politics or weekend hobbies.

The Deadlines That Can End Your Case

Most wrongful termination claims in Denver die at the filing deadline. The strongest case in the world is worthless once the window closes.

Colorado Civil Rights Division: 300 days from the date you received notice of the discriminatory act. Miss it and the claim is permanently barred under C.R.S. § 24-34-403.⁶
EEOC: the general federal deadline is 180 days, but because Colorado has its own anti-discrimination agency, that extends to 300 days for most charges. Weekends and holidays count. If the last day lands on a weekend or holiday, you get until the next business day.⁷
OSHA whistleblower complaints: 30 days from the retaliation.

For ongoing harassment, the EEOC clock runs from the last incident, and the agency can look back at earlier incidents in the same pattern.⁷ A termination has a fixed date. The clock starts the day you are told you are fired.

What to Do in the First Few Days

The period right after a firing is when the most important decisions get made. File for Colorado unemployment benefits immediately; a wrongful termination claim takes months or years to resolve, and you need income in the meantime.

Colorado law gives you the right to see your personnel file. Under C.R.S. § 8-2-129, a former employee gets one inspection after termination.⁸ Send a written request to HR before the file can be sanitized. Ask for performance reviews, disciplinary records, and signed agreements. Consistently positive reviews flatly contradict an employer who now says you were fired for poor performance.

Save everything on a personal device while you still have access: emails, texts, voicemails, calendar entries, written exchanges with supervisors or HR. Write down what was said in the termination meeting while it is fresh, including who was present. If your manager gave one reason verbally and the paperwork gave another, note both. Inconsistent explanations are among the strongest indicators of pretext.

Consider sending the employer a written preservation letter asking them to retain all records related to your employment and termination. Companies routinely delete emails and overwrite data in the normal course of IT work. A preservation letter puts them on notice that destroying relevant evidence carries legal consequences.

Filing a Complaint With the CCRD or EEOC

For discrimination and retaliation claims, the first formal step is filing a charge with the Colorado Civil Rights Division or the federal EEOC. The CCRD takes intake questionnaires electronically through its CaseConnect system.⁹ A complaint is legally filed only when the Division has received a jurisdictionally valid, signed, and verified version. From that point, the CCRD has 450 days to complete its administrative process.¹⁰

The CCRD and EEOC have a worksharing agreement, so a filing with one agency generally cross-files with the other. If you are unsure which to pick, filing with the CCRD inside the 300-day window preserves both the state and the federal claim.

Filing an agency complaint is not the same as filing a lawsuit. For claims under Title VII or the ADA, you cannot go to federal court until the EEOC issues a Notice of Right to Sue, and the agency generally must have at least 180 days to work the case first. Age discrimination claims under the ADEA work differently; no right-to-sue letter is required, and you can file suit 60 days after submitting your EEOC charge.¹¹ Equal Pay Act claims skip the EEOC entirely and go straight to court within two years of the last discriminatory paycheck, or three years for a willful violation.⁷

Public policy wrongful discharge claims under Martin Marietta are tort claims filed directly in Colorado state court and do not require an agency filing first. They carry their own statute of limitations, so getting legal advice early is the safest way to avoid missing it.

What You Can Recover

Recovery in a wrongful termination case depends on whether you proceed under state law, federal law, or both. The categories overlap, but the caps differ.

Back pay: wages and benefits lost from the date of the illegal firing through judgment or settlement.¹²
Front pay: projected future earnings when reinstatement is not practical. Courts typically limit front pay to roughly three to five years.
Compensatory damages: out-of-pocket costs caused by the firing, plus compensation for emotional harm such as anxiety or depression. If you claim emotional distress, expect the employer to request your mental health records.¹²
Reinstatement: a court order placing you back in your former position with seniority restored. Available, but uncommon, because the working relationship has usually broken down.

Under Title VII and the ADA, combined compensatory and punitive damages are capped by employer size: $50,000 for 15–100 employees, $100,000 for 101–200, $200,000 for 201–500, and $300,000 for more than 500.¹² Back pay and front pay sit outside those caps. For workers at large Denver employers, the $300,000 federal ceiling can feel low relative to the harm. Filing under CADA in state court may offer different remedies, and an attorney can compare the paths based on your facts.

Even a strong case shrinks if you did not look for another job. The duty to mitigate requires a genuine effort. You do not have to take a demotion or something far below your skill level, but you do need to apply for comparable positions and keep records of applications, interviews, and responses. Those records are the answer if the employer later argues you failed to mitigate.

Severance Offers and What You May Be Signing Away

Many Denver employers offer severance in exchange for a signed release of claims. A release typically waives your right to sue, though it cannot waive your right to file a charge with the EEOC, and it cannot waive a claim for Colorado unemployment benefits.

If you are 40 or older, the Older Workers Benefit Protection Act imposes strict rules on any waiver of age discrimination claims. A valid waiver must:¹³

Be written in plain language you can actually understand.
Specifically reference the Age Discrimination in Employment Act by name.
Give you at least 21 days to consider the agreement, or 45 days if the severance is part of a group layoff.
Give you 7 days after signing to revoke it.
Advise you in writing to consult an attorney.
Offer you something of value beyond what you were already owed.

Skip any of these and the age discrimination waiver is unenforceable. The 7-day revocation period cannot be shortened, even by mutual agreement.¹³ An employer who pressures you to sign today or lose the offer is creating the exact pressure the OWBPA was designed to prevent.

Many Denver employment attorneys offer free initial consultations and take wrongful termination cases on contingency, meaning no fee unless you recover. The 300-day CCRD and EEOC deadline sounds generous, but building a solid case takes longer than most people expect. The strongest claims are the ones where a lawyer gets involved early.
