What if someone outside the company sexually harasses a worker? 

On Behalf of | Aug 3, 2026 | sexual harassment |

Sexual harassment by a customer, vendor or contractor may leave you feeling exposed and unsure where to turn. An outsider’s role can make the harm seem harder to address.

If you face such behavior, workplace protections may still apply. Knowing what your employer should do can show when its failure to act has legal consequences.

When outside conduct creates employer responsibility

Your employer may face liability if it ignores sexual harassment by a nonemployee. In Pennsylvania, the Pennsylvania Human Relations Act (PHRA) treats such misconduct as workplace sex discrimination. The law also provides a process for seeking relief.

Pennsylvania Human Relations Commission (PHRC) guidelines state that responsibility may arise if management knew or should have known but failed to take prompt and proper corrective action. The agency also weighs the company’s control over the offender. For example, a restaurant can ban a customer who makes sexual comments to a server. That authority often helps define a reasonable response.

How to report the conduct

Follow company policy and submit a written report. Include dates, statements, actions, witnesses and prior complaints. This account can give management notice and preserve key facts.

If the company does not act, you may file with the PHRC or the Equal Employment Opportunity Commission (EEOC). A PHRC complaint generally must be filed within 180 days of the alleged discrimination. An EEOC charge often has a 300-day deadline, while state law may cover the same basis.

The law also bars retaliation for a reasonable, good-faith complaint. A demotion or cut in hours may support an allegation if the report caused that adverse action.

Why timely guidance matters

Emails, messages and witness names can show what occurred and when management learned about it. This evidence may also link a later employment decision to your report.

An attorney can assess the facts, identify viable claims and calculate the correct filing period. Prompt advice matters because an internal grievance generally does not extend an agency deadline.
