How would you feel if you were doing exactly the same job as the person next to you but he or she was being paid more than you?
My guess is that you wouldn’t be feeling too happy as the principles of fairness and equality would clearly be broken.
It also raises the discussion of discrimination if one person doing the same job as another is paid less.
The video below however shows that it’s not just humans who get upset if someone else is paid more for doing the same job.
The video shows a researcher getting some Capuchin monkeys to each undertake the same job (handing the researcher a rock) but the rewards given are different. One of the monkeys gets a slice of cucumber whilst the other gets a tasty grape.
Now, how would you feel if your colleague was given a tasty grape whilst you were given the cucumber?
Well, the monkey wasn’t too happy…
