A US judge has ruled in favor of Zuru, a New Zealand toy company, to release the contact details of former employees who posted anonymous reviews on Glassdoor. The company intends to sue the reviewers in New Zealand for defamation. Glassdoor had argued that the reviews were opinions and did not contain defamatory statements, but the judge ruled that the company had shown it had suffered a loss due to the reviews. The decision has raised concerns about the anonymity of reviewers on Glassdoor.
