This is the problem with management roles. Managers opportunity to find new job is so low they are forced to think they are part of the company. The company does not think the same. The same is not true for IC devs, this may not be for long, but currently this the case. I hope people be honest at least over internet.
When I say we I don't just mean "me". I mean all levels up to the CEO. And we demonstrate that all the time, it's not just something we say.
Again, this is still a business, it's not a non-profit, but there is alignment between treating people well and having a good business and finding more great people. Randomly firing people or abusing people, is just stupid. Please don't work at places that do that, not only because you'll get fired, but because that business is hurting its long term success.
