There's a flip side you're skipping over. Going above and beyond has an opportunity cost, you are spending time and effort on a chance of improving your employment situation at the cost of spending that time and energy elsewhere, places where it _could_ be a guarantee at a better life. For example, spending time doing things you love, or spending time just being around the people that you love. In my opinion the optimised outcome is a good life, not good employment.
