Illegal harassment is unwelcome conduct based on a protected characteristic (sex, race, religion, age, disability and others) that is severe or pervasive enough to create a hostile work environment, or that is tied to job decisions. General rudeness isn't covered. But when conduct crosses the line, the strength of a claim depends largely on documentation.
Keep a contemporaneous log
For each incident, record:
- Date, time and location
- What was said or done, as close to verbatim as possible
- Who did it and who witnessed it
- How you responded
- Any effect on your work
Keep the log somewhere the employer can't access, a personal notebook or a personal email account, not your work computer. Contemporaneous notes carry far more weight than memories reconstructed later.
Preserve the evidence
Save texts, emails, chat messages, photos and voicemails. Forward work emails to a personal account only if your employer's policies permit; otherwise, photograph the screen. Don't record conversations without checking your state's consent laws.

Report it, in writing
Most employers can only be held responsible for co-worker harassment if they knew about it and failed to act, and an employer's defense to supervisor harassment often depends on whether you used the complaint process. Report through the channel in the handbook, in writing, and keep a copy. If the harasser is the person you'd report to, go above them or to HR.
After you report
Retaliation (demotion, schedule cuts, exclusion, termination) for a good-faith complaint is itself illegal, and often easier to prove than the underlying harassment. Keep logging.
Agency deadlines
To bring a federal claim, you generally must file a charge with the EEOC within 180 days (300 in most states) of the last incident. State agencies have their own windows.

Take care of yourself
Harassment takes a toll. Employee assistance programs and outside counselors are confidential, and documentation of the impact on your health is relevant to damages.

How to write a complaint that's hard to ignore
A vague complaint ("my coworker is making things uncomfortable") gives an employer room to treat it as a personality clash. A specific one puts the company on notice of possible illegal harassment and triggers its obligation to respond.
Keep it factual and organized:
- Say plainly that you're making a harassment complaint.
- List specific incidents with dates, what was said or done, and who was present.
- Connect the conduct to the protected characteristic if you believe it's involved, for example, "I believe these comments are about my national origin."
- Describe how it affects your work.
- Ask for something concrete, like an investigation and not being scheduled alone with the person.
- Mention that you're concerned about retaliation.
Send it by email or another method that creates a timestamp, and save a copy in your personal records. Stick to what you saw and heard. Skip the adjectives that invite argument, and don't speculate about the harasser's private life. If you keep a log, you can offer to share it rather than packing every detail into the first message.
What to expect once HR investigates
After a complaint, a company that takes it seriously will usually interview you, the person accused and any witnesses, and review messages or other evidence. The process can take days or weeks.
Keep two things in mind. First, HR works for the employer. Its job is to protect the company, which often lines up with stopping harassment but not always. Second, confidentiality has limits. Investigators generally share information only as needed, but the accused will usually learn the substance of the complaint.
During your interview, bring your log and copies of evidence, and offer the names of witnesses. Ask what interim steps will be taken while the investigation is open. Any separation measures shouldn't fall on you in a way that looks like punishment, such as being moved to a worse shift.
When it's over, ask about the outcome in writing. The company may not share discipline details, but you can ask whether your complaint was substantiated and what will change. Keep logging afterward, including anything that feels like payback. If the conduct continues or you're penalized for reporting, consider an attorney, the EEOC or your state agency.

A realistic example
Consider a hypothetical: Nina works in a clinic's billing office. A coworker starts making comments about her religion, first as "jokes," then in front of patients' families, and leaves a mocking note on her desk.
Nina starts a log in a personal notebook, dating each incident and noting who heard it. She photographs the note. After the third incident in two weeks, she emails HR a complaint listing each event, saying she believes the comments target her religion, and asking not to be scheduled alone with the coworker.
HR interviews her and the two witnesses she named. A week later, her supervisor moves her to evening shifts, which she didn't request. Nina logs the change and asks HR by email why it happened.
When HR's answer doesn't explain the timing, Nina meets with an employment attorney, bringing her log, the photo and her email trail. The attorney reviews both the harassment and the possible retaliation, and checks the agency filing deadline.
Common questions
Does workplace harassment have to be sexual to be illegal?
No. Sexual harassment gets the most attention, but harassment based on race, religion, national origin, age, disability, pregnancy and other protected characteristics can be just as unlawful. The question is whether the conduct targets you because of a protected characteristic and is severe or pervasive enough to change your working conditions. State and local laws may protect additional characteristics.
What should I do if HR ignores my harassment complaint?
Follow up in writing, restating the complaint and asking for a response by a specific date. If nothing changes, escalate to a higher manager or another channel listed in the handbook. Keep documenting incidents and your follow-ups. An employer's failure to act on a report can strengthen a legal claim, so this is also a good time to talk with an attorney.
Can I quit because of harassment and still have a claim?
Possibly, but the bar is high. Courts may treat a resignation as a firing, often called constructive discharge, when working conditions became so intolerable that a reasonable person would feel forced to leave. That usually requires strong documentation and, in many cases, evidence you gave the employer a chance to fix things. If you can, talk to an attorney before resigning.
Send your complaint by email rather than only in person, and keep a copy outside your work accounts.
