Wow. The delta between the entitlement that you have for your "second full time job" and your expectations vs the reality of the history of people going to work is pretty astounding.
Yea my second full time job wasn't given to me. I worked hard and I chose them to do business with. I am the CEO of my "enterprise". So this isn't an entitlement. It's what I worked hard for.
When I interviewed there they thought they were interviewing me. I was interviewing them. I chose them to work there they didn't pick me. I don't owe them anything accept for what I agreed to when I contracted out my future self.
I enjoy the business relationship I have with them. If the terms of that relationship change. Then I will re-evaluate and make the best decision for my "Company". It' really as simple as that.
