Yes, an employer may use an algorithm when deciding to fire someone, but that does not by itself make the firing lawful. The answer depends on where you work, what the tool did, and whether the employer’s decision violated a law that applies to you. U.S. law does not establish a general rule that every algorithm-assisted firing is either allowed or prohibited.

What makes an algorithm-assisted firing lawful or unlawful?

The word “algorithm” is not a legal conclusion. A tool might rank employees, assess performance, flag conduct, or simply provide information that a manager considers alongside other evidence. The important questions are what employment decision the tool influenced, how the employer used its output, and whether that process violated an applicable law.

Federal Title VII addresses discriminatory employment practices and includes a provision concerning professionally developed ability tests. It requires that a test and its administration or use not be designed, intended, or used to discriminate on protected grounds. That can matter when a tool functions as part of an employment assessment, but it does not make every algorithm-assisted firing automatically lawful or unlawful. The statute is not a general approval or ban on firing people with algorithmic assistance.

New York City Commission on Human Rights guidance likewise says covered entities remain responsible for discriminatory actions and decisions made through AI and other technology; an employer cannot avoid liability for unlawful discrimination by blaming the technology. The tool’s involvement alone, however, does not establish that a particular firing was discriminatory.

Does New York City’s algorithm law cover firing decisions?

Not as a general firing rule. New York City’s Local Law 144 applies to covered automated employment decision tools used to screen candidates or employees for an employment decision. The New York City Administrative Code defines that decision as screening candidates for employment or employees for promotion. That defined scope should not be stretched to mean that the law generally regulates termination decisions.

For covered uses, the law requires an independent bias audit conducted no more than one year before use and public posting of a summary of the audit results before use. Covered candidates and employees who reside in New York City must receive notice at least ten business days before use. The notice must say that the tool will be used, identify the qualifications and characteristics it assesses, and provide an opportunity to request an alternative selection process or accommodation. If data-type, source, and retention information is not already on the employer’s website, it must be made available on request, subject to legal exceptions.

These requirements are distinct from the Commission on Human Rights’ broader guidance about responsibility for discrimination involving technology. The Department of Consumer and Worker Protection says people can complain if an employer or employment agency used a covered tool but failed to conduct the required audit, post its summary, or provide required notice. Local Law 144 took effect January 1, 2023; the agency says enforcement began July 5, 2023.

What is changing in Colorado?

Colorado enacted SB 26-189, a law addressing automated decision-making technology that materially influences consequential decisions, including employment decisions. The legislature’s summary describes covered technology as processing personal data and using computation to generate an output used to make, guide, or assist an individual decision.

The law takes effect January 1, 2027. As of October 4, 2026, it is enacted but not yet in effect. Colorado’s Attorney General is in rulemaking. The official sources reviewed do not establish the full operational requirements here, so do not treat the future Colorado law as an already-effective rule or assume particular audit, notice, accommodation, explanation, or human-review requirements.

How do the federal baseline, New York City, and Colorado differ?

Jurisdiction Employment decisions addressed Status on October 4, 2026 What the cited official sources establish
Federal: Title VII Discriminatory employment practices; the statute also addresses professionally developed ability tests and their use. Federal statute; no new effective date identified in the cited source. Discrimination law can apply to employment decision procedures. A general algorithm-specific firing rule is not stated in the Title VII source.
New York City: Local Law 144 Screening candidates for employment or employees for promotion; not a general termination rule. Effective January 1, 2023. DCWP enforcement began July 5, 2023. For covered uses, the code requires a recent independent bias audit, a public summary, and advance notice with specified information and an opportunity to request an alternative process or accommodation.
Colorado: SB 26-189 Automated decision-making technology materially influencing consequential decisions, including employment. Enacted, but effective January 1, 2027; not yet in effect on October 4, 2026. The official summary describes covered technology and decision scope. The detailed operational requirements are not stated in the cited summary.

This is not a 50-state comparison. The cited sources establish these examples but do not show that other states have no applicable rules.

What should you do if an algorithm may have contributed to your firing?

  1. Write down the basic facts. Record when you were told about the firing, who communicated it, what reason was given, and anything you know about the tool’s role in the decision. Keep contemporaneous notes and copies of communications you already lawfully possess.
  2. Identify the location and employment context. Note where you worked, whether you lived in New York City if that is relevant, and whether a contract, union agreement, civil-service status, or other workplace arrangement applies. The rules and possible routes for a challenge can depend on these details.
  3. Ask what role the tool played. If you communicate with the employer, ask whether an automated tool was used, what decision it informed, and what process was followed. In a covered New York City screening process, the law specifies notice and certain information rights; those screening rules should not be assumed to apply to a firing.
  4. Get advice promptly. Contact a qualified employment lawyer or the relevant labor or civil-rights agency for advice specific to your location and facts. The sources described here do not determine an individual worker’s filing deadline, remedy, or likelihood of success.

What can’t be decided from the fact that software was used?

Knowing only that an employer used an algorithm does not establish whether the tool caused the firing, whether the employer relied on its output, whether a legally protected right was violated, or what remedy may be available. A case-specific assessment may also involve contract, union, civil-service, whistleblower, retaliation, disability-accommodation, privacy, or other jurisdiction-specific rules. The sources discussed here do not resolve those questions for an individual worker.
