Blind, the anonymous employee chat app for employees, polled thousand of people who work at tech companies to ask them the kinds of sensitive questions that you normally can't ask: Do you think you are paid fairly? Are you interested in leaving your job?

Not surprisingly, those two things were closely related. Those companies that had the most employees unhappy with their pay also had the most employees interested in leaving.

There were a lot of other interesting tidbits revealed in the survey as well. The employees happiest with their pay are not working at Google or Facebook, for example, they are at Netflix, followed by Dropbox.

Of course, this survey isn't representative of the companies — it reflects only the opinions of employees who choose to use the Blind app. But those opinions provide an interesting window into the mood, at least among some staffers, within tech's biggest companies.
