As of my knowledge cutoff in September 2021, Glassdoor did not have a specific policy of removing reviews after a certain period of time. Reviews on Glassdoor typically remain on the platform unless they are found to violate Glassdoor’s review policies or if the user who posted the review decides to delete it.
However, it’s important to note that Glassdoor’s policies and practices may have changed since then. It’s always a good idea to consult Glassdoor’s official documentation or contact their support for the most up-to-date information on how they handle the removal of reviews and their retention policies.
If you have concerns about a specific review or want to understand more about Glassdoor’s policies regarding review removal, it’s best to reach out to Glassdoor directly for clarification. They can provide you with specific information and guidance based on their current policies and practices.
