This is one of those findings in psychology that's always seemed suspect to me.<p>What is salary if not a reward for work done on an ongoing basis? The vast majority of people would not do their jobs for free; they need that reward for them to keep doing it.<p>Similarly, I've tried harder at my current job than at previous jobs because the performance review, promotion process, and merit bonus/raise programs are much more rigorous. My employer hasn't gotten more and better work out of me as a result, and I've gotten better promotions and raises as a result too. Is this not a "reward"? I've seen, with my own eyes, coworkers putting in long hours at crunch time for a shot at a better annual bonus or higher chances of promotion (at companies where effort is fairly evaluated and rewarded).<p>What possible levers does a business have to pull to entice performance from its employees if not monetary compensation? Every other reward in lieu of money is (correctly) perceived to deeply cynical. Businesses exists to make money, and if you make them more money but instead of sharing that with you they just give you something intangible like praise, then they're ripping you off.<p>If effort can't be rewarded with money, then shouldn't the entire economy collapse? That is the basis of capitalism after all. Something seems to be deeply off with these studies.
