In most states you can refuse to work with a registered sex offender, but your employer can fire you for that refusal. At-will employment gives both sides that freedom, and a coworker’s registry status is not, by itself, a legal reason to walk off the job. You gain real protection only in two situations: when you have a specific, credible safety threat, or when you and other coworkers raise the concern together.
What At-Will Employment Means for Your Refusal
Every state except Montana follows the at-will employment doctrine. Either side can end the relationship at any time, for almost any reason, as long as the reason isn’t illegal (such as firing someone because of race or religion).1USAGov. Termination Guidance for Employers Refusing to work alongside a particular coworker is not a legally protected act under federal law.
From your employer’s side, refusing to perform assigned duties or work in assigned areas looks like insubordination. They don’t need any other justification to let you go.2Legal Information Institute. Employment-at-will Doctrine Saying “I won’t work with that person” puts you on legally thin ice unless you can tie the refusal to one of the exceptions below.
The OSHA Safety Exception and How Narrow It Is
Federal law gives every employee the right to a workplace free from recognized hazards likely to cause death or serious physical harm.3Occupational Safety and Health Administration. OSH Act of 1970 – Section 5 Duties OSHA enforces that right, and employees can refuse work in situations where they’d be exposed to a genuine hazard.4Occupational Safety and Health Administration. Worker Rights and Protections
The bar for a valid work refusal under OSHA is high. You need a reasonable, good-faith belief that you face an imminent threat of serious physical harm or death. General unease about a coworker’s past convictions doesn’t meet that standard. Neither does a vague sense that something might happen. The threat has to be specific and immediate: closer to “this person has made direct threats against me at work” than “I found his name on a registry.”
If you do raise a legitimate safety concern, Section 11(c) of the OSH Act prohibits your employer from firing, demoting, transferring, or otherwise punishing you for filing a safety complaint or reporting hazardous conditions.5Whistleblowers.gov. Occupational Safety and Health Act (OSH Act), Section 11(c) The complaint has to be made in good faith about an actual workplace safety issue. Reporting a specific, credible threat and getting fired for it can support a retaliation claim. Complaining about someone’s criminal history in general terms, without identifying a concrete danger, probably won’t.
Acting Together With Coworkers Changes the Analysis
The protection most people overlook here is the National Labor Relations Act. Section 7 gives employees the right to engage in “concerted activities for the purpose of collective bargaining or other mutual aid or protection.”6Office of the Law Revision Counsel. 29 USC 157 – Right of Employees as to Organization, Collective Bargaining, etc. If two or more employees act together to address a shared workplace concern, that activity is protected regardless of whether a union is involved.
The protection extends to collective safety concerns about a coworker. Employees can talk with each other about working conditions, bring group complaints to management, and even participate in a concerted refusal to work in unsafe conditions. Employers cannot fire, discipline, or threaten employees for that kind of protected activity.7National Labor Relations Board. Concerted Activity
The NLRB has handled a case that fits this scenario closely. Women working the overnight shift at a plastics manufacturing plant discussed concerns about a new supervisor they learned was a registered sex offender. They asked for a group meeting with HR, and were instead called into individual meetings and disciplined. One employee was fired, and others were demoted. After an NLRB investigation, the employer settled by restoring all of the employees to their former positions with full back pay.8National Labor Relations Board. Protected Concerted Activity
The distinction is between acting alone and acting with others. An individual employee who unilaterally refuses to work with a coworker has little legal protection. Employees who discuss the situation among themselves and collectively bring concerns to management are engaging in textbook protected concerted activity. Protection can still be lost if the conduct becomes egregiously offensive or involves knowingly false statements about the coworker.7National Labor Relations Board. Concerted Activity
Why Discrimination and Harassment Claims Won’t Fit
Some employees assume that working near a convicted sex offender is automatically a hostile work environment. Under federal law, it isn’t. A hostile work environment claim requires harassment based on a protected characteristic: race, color, religion, national origin, sex, disability, age (40 or older), or genetic information.9U.S. Equal Employment Opportunity Commission. Questions and Answers for Employees – Harassment at Work Criminal history isn’t on that list. Even when harassment is based on a protected characteristic, it has to be severe or frequent enough that a reasonable person would find the environment abusive.10U.S. Equal Employment Opportunity Commission. Small Business Fact Sheet – Harassment in the Workplace A coworker’s mere presence, however uncomfortable, doesn’t meet that threshold.
The flip side matters too. Being a registered sex offender is not a protected class. Title VII prohibits employment discrimination based on race, color, religion, sex, and national origin.11U.S. Equal Employment Opportunity Commission. Title VII of the Civil Rights Act of 1964 Other federal laws add protections for disability, age, and genetic information.12U.S. Equal Employment Opportunity Commission. Who Is Protected from Employment Discrimination? Criminal history is absent from every list. An employer can lawfully consider a person’s sex offender status when making assignment or termination decisions, so long as its screening practices don’t produce an unjustified disparate racial impact under EEOC guidance.13U.S. Equal Employment Opportunity Commission. Enforcement Guidance on the Consideration of Arrest and Conviction Records in Employment Decisions under Title VII of the Civil Rights Act
What to Do Instead of a Flat Refusal
How you handle the first few days will largely determine whether you end up protected or exposed. A few concrete moves keep your options open:
- Document specific behavior, not status. Keep a written log of anything the coworker does or says at work that makes you feel unsafe. “Found his name on the registry” is context. “He made an inappropriate comment to the intern on Tuesday” is something HR can act on.
- Read the employee handbook. Look for the sections on workplace safety, grievance procedures, and employee conduct. Knowing the formal reporting process before you need it keeps you from skipping steps that matter later.
- Report through official channels. Bring the concern to HR or your direct manager, and frame it around workplace safety rather than the coworker’s past. “I have specific safety concerns about a coworker’s behavior” carries more legal weight than “I don’t want to work with a sex offender.”
- Talk with coworkers who share the concern. If others feel the same way, raising the issue as a group gives you NLRA concerted-activity protection you don’t have acting alone. The plastics-plant case shows this can hold even when the employer initially retaliates.8National Labor Relations Board. Protected Concerted Activity
- Ask for a schedule or location change. Rather than framing the situation as a refusal, ask whether a shift change, transfer, or reassignment is possible. That lets you address the concern without creating a confrontation that puts your job at risk.
Your employer also has an independent legal duty to provide a workplace free from recognized hazards.3Occupational Safety and Health Administration. OSH Act of 1970 – Section 5 Duties That means credible safety concerns have to be taken seriously and investigated. If your employer ignores a specific, documented complaint and something goes wrong, its failure to act strengthens any later claim. If you skip the reporting process and go straight to a public refusal, you’ve given your employer a clean reason to fire you.
Don’t Broadcast the Information Around the Office
Sex offender registries are public records, and the Dru Sjodin National Sex Offender Public Website maintained by the U.S. Department of Justice provides nationwide access. Checking a registry is not illegal, and sharing publicly available, accurate information is generally not defamation, since truth is a complete defense.
How you share it still matters. Quietly telling a close coworker about a safety concern is different from emailing the office or posting in a group chat. Broadcasting the information can be treated as workplace harassment by your employer even when everything you say is accurate. Your employer can discipline or fire you for conduct that disrupts the workplace, and mass-distributing a coworker’s criminal history is exactly the sort of thing HR departments treat as a serious policy violation.
There is also a defamation risk if you go beyond what the registry says or embellish the details. Accuracy is your only reliable shield. Stick to verifiable facts, don’t speculate, and route your concerns through HR or management instead of running an informal awareness campaign. That approach preserves the legal protections you actually have and avoids handing your employer a reason to end the conversation with your termination.
