You can pay Glassdoor to become an "Engaged Employer": http://resources.glassdoor.com/contact.html?channel=homepage...

So yes, Glassdoor's intensive structure is aligned to make employers happy. They don't take any income from individual review contributors or readers.

Hmm, though this is cause to doubt, it is still only one cause.

However, it seems that their business model is then catered, at this time, to employers and they have made themselves a niche area in the reputation management sector. Though not alarming at this time, I can see this going south quickly and without warning (Equihax for example)
