Glassdoor allow vindictive employees to pose as former employees to attempt to damage reputation. They have no interest in authenticating the reviewer. Not doing enough to stop fake reviews. Glassdoor could be an excellent tool, but they do nothing if your company receives fake reviews. We have had 4 fake reviews full of lies and Glassdoor literally do nothing about it even though we can provide them with all the evidence they need to show they are categorically fake reviews.
