What to Do if a Coworker is Sexually Harassing You

Coworker harassment traps people in a specific way: you share shifts, projects, sometimes a manager who likes them. Doing nothing feels safer than making it "a thing." But California law has a clear answer for this exact situation, and the sequence below protects you at every step - including from the backlash you're worried about.

Step 1: Write Down What Has Already Happened

Tonight, at home, not on a work device: every incident you can remember, with dates (approximate is fine), what was said or done, where, and who was around. Then keep the log going - short entries, same day as events. Contemporaneous notes carry real evidentiary weight, and this document will drive every later step. Save existing evidence now: screenshots of messages, photos of notes, the group-chat thread before you lose access.

Step 2: Tell Them to Stop - If It's Safe, and Only Once

A single clear written line ("Don't send me messages like this again") removes the "it was mutual banter" defense forever. This step is optional - if the person is volatile or the conduct is severe, skip straight to Step 3. You are never legally required to confront your harasser.

Step 3: Report It in Writing, Up, Not Sideways

This is the step that changes everything legally. The moment your employer knows, California law obligates them to act - for coworker harassment, the employer is liable if it knew or should have known and failed to take prompt, effective action. Make "knowing" undeniable: a dated email to your supervisor or HR, factual and calm, using the phrase "sexual harassment," listing incidents from your log. Keep the sent copy at home. If your manager is friends with the harasser, go over their head - nothing requires you to report to the person least likely to act.

Step 4: Watch What Happens Next - to the Conduct and to You

Two clocks start. The employer's: are they investigating, separating you from the harasser, actually fixing it? Silence and shrugs are now evidence against them. Yours: does your schedule, workload, or treatment change after you complained? Retaliation - even for complaining about a coworker - is separately illegal, and adverse action within 90 days of your complaint is presumed retaliatory. Log both clocks in the same file. If HR stalls, here is how long they actually have and what to do when nothing happens.

Step 5: Know When to Go Outside

You do not have to wait for the internal process to fail completely. You can file with California's Civil Rights Department (three years) or the EEOC (300 days) at any point, and you can talk to a lawyer - free and privileged - at ANY step of this sequence, including before Step 1. Go outside sooner when: the conduct is physical, the harasser has any authority over you, the employer's response is punishing you instead of them, or you are thinking about quitting. On that last one: talk to a lawyer before resigning - done right, an intolerable-conditions resignation can be treated as a firing; done impulsively, it can shrink your case.

What You Never Have to Accept

Not "that's just how he is." Not "you two work it out." Not a transfer that makes YOUR job worse while theirs stays untouched. The law puts the burden of fixing harassment on the employer, not on the target's willingness to absorb it.
