If the kununu review rules have been adhered to then kununu doesn’t generally delete any reviews posted.
If kununu were to select reviews to delete then this would also reduce the credibility of the positive reviews. In our extensive experience we can say that taking such a step would result in a wave of indignation across all social media and lead to long-term damage to the image of a company.
kununu would encourage you to start using its comment feature instead. It allows you to communicate your own point of view about the facts of the situation in your company. It is free of charge and also means that you get the final word in response to reviews on kununu.com.
Reviewers are not able to respond to any comments/statements you post, nor are they able to enter into a discussion with other users. By posting objective comments you are demonstrating your respect for your employees, and your positive role as a moderator will detract from the initial negative review.
If you have any other questions about kununu, a good place to find answers is the kununu FAQ.
