My only concern with Glassdoor is that their review removal policy is unclear. They have removed mine and my friend's reviews of a nonprofit we worked for. The reviews were nonoffensive, but they were negative, as the experience working for the org was quite bad, and equally, the org was not creating any significant impact. So both things combined made it not a very friendly workspace.
It's not clear to me why the reviews were removed, but I spotted that there is an option to report a review. So I wonder if an org can also game the system by encouraging multiple people to report negative reviews.
I also worry that people with negative experiences are more inclined to leave reviews. So, e.g. an org can have one negative review and zero positive because satisfied employees didn't feel motivated to post (didn't have the urgency to warn others).
So I wonder if there is a healthy way to encourage reviews in general. Probably this post is one since it does not come directly from an employer.
I agree with the rule that this kind of reviews would be beneficial. If I had read my former employer's reviews now, I would not have gone to work with them (I would avoid months of ineffective work in hostile conditions and burnout). Thanks to the org having a sufficient number of reviews on Glassdor now, you can see the inefficiencies at work mentioned, the lack of impact-focus, and not great treatment of employees, which would be a significant warning for me.
Again, positive reviews, talking about hard work, impact focus, kind colleagues (that, at the moment, I would leave for CE if I was leaving the org) would probably encourage me to apply because I care for impact but I also care about working with intelligent and kind people in an ambitious, startup work environment.
