Interesting what you say and I was surprised to read about Google because one imagines that people would never leave that company because they are supposed to pay very well, which assumes that the good working environment and valuation keeps people attached to their jobs, there is intrinsic motivation, however I think some companies do not value their staff because part of the valuation is money and there are companies that pay as if we were doing a favor and that our time is not worth, I say this for mine, so soon I will hone my wings to fly.
Most will always complain about what they get paid, but I wonder how many people have really done the math on what they are worth to the company?
