I worked with an engineer with this mindset of, "the company is out to get me" at an early stage startup. They left after a few years and started their own company. They couldn't recruit and grow. I turned down their offer because I didn't trust them. I didn't trust them because I was well aware of their distrustful mindset when working in a small group setting.

I had a different mindset during the early stages of the startup, one closer to a model of trust with the company on compensation, quality, and level of effort. I also left to start my own company and I've had no trouble attracting people, both employees and sub-contractors.

There is some merit to an adversarial mindset but it's a liability in the early stages of a company and it leaves a lasting impression on your reputation.
