It's not about feeling like I own the company or not. I make decisions based on what I believe is right and efficient for the problem at hand. If I were CEO I would have different contexts and problems at hand probably...
They all miss the point. Having "ownership" is caring like its yours. Making decisions that make sense, and you would do in yours. Your answer is perfect!
Ofcourse you should not have the "minimal effort police" in mind, but you also should not work your balls off for nothing.
No, I'm not the owner but I expect some autonomy in my area and wouldn't work in any other way (e.g. just taking orders mindlessly). Same would happen in any position up the ladder.
