Two problems, one panic
The Glassdoor review might be removable. The LinkedIn screenshot with 40,000 impressions is a separate asset you don't control. HR teams conflate them and draft one response that satisfies neither audience.
Triage: assess the review for removal eligibility first. Parallel track: comms handles social spread without amplifying the Glassdoor URL in your corporate response.
What not to post publicly
Don't threaten the LinkedIn poster. Don't call the Glassdoor review "fake" without qualification if you haven't verified it. Don't ask employees to astroturf positive reviews — journalists love that story and Glassdoor penalizes it.
A measured statement acknowledging you're reviewing the feedback internally buys time without conceding defamation.
Resolution sequence
We removed two embedded factual falsehoods from the original Glassdoor review through dispute — the opinion parts stayed. Comms issued a single statement. LinkedIn fire died in five days without a flame war.
Viral moments need parallel workstreams. Our Glassdoor Review Removal team coordinates with client comms so legal removal and public messaging don't collide.
