Tech workers are the envy of labor market — they earn some of the highest starting salaries and often command top-notch benefits.

But money doesn't always buy satisfaction. Entrepreneur reports that tech workers in major American cities earn an average of $135,000 and yet, a survey of 6,000 tech workers conducted by workplace app Blind and reported by Quartz found that over 60 percent feel they aren't being paid enough.

"This is in an industry," Quartz reports, "where interns can make over $50 an hour, new grads can get $100,000 signing bonuses, and the average employee makes more than double the national average in the U.S."

The survey also breaks down how tech workers feel about their pay by company. The five tech companies with the highest percentage of employees who felt they were underpaid shared one important characteristic: They were all founded before 1998.

Cisco, Intel, Expedia, VMware and Microsoft employees were the most likely to say that they did not make enough money. Cisco had the highest percentage of dissatisfied employees, with 80 percent telling Blind that they did not feel adequately compensated. Facebook employees, on the other hand, were the most like to say that they are overpaid, with 13.8 percent saying that they felt their employer was overly generous.

Netflix is the company that might be hitting the nail on the head when it comes to compensating their employees. The lion's share of workers at the entertainment company — 81 percent — told Blind that they were fairly compensated.
