My last company sent out multiple “Please leave a positive review on Glassdoor” emails as we were trying to hire more. I never felt actually pressured to leave a review, positive or not, from those requests. I didn’t (and it would not have been a positive one, if I did at that particular point in my tenure) and there were no repercussions. There were a few negative reviews added at the time, but there’s no way of knowing if those were a response to the email or not. This was a large company, so maybe that matters to how people feel about it.
