And it's likely thar at least some of those grievances where born out of misconduct by the company. Bringing us back to my position that all companies lie and screw over workers, that the ones that look good just mean you aren't witnessing it.
Find me any situation anywhere in the world where there are no bad actors.
Companies are made up of people, this happens everywhere. You're just describing life. This is not a problem specific to "companies".
Or, on the other hand, I've seen companies offering to enter you into gift card drawings to relate your positive experience with them on glassdoor, etc. :eyeroll: To me, glassdoor and the like are similar to Amazon reviews, you can't trust them, but it sometimes feels like the only way to _possibly_ get the information you're seeking.
Like any rating system it is biased towards people with grievances, as they are motivated to look for an outlet to express that grievance.
