People should never be wasted ..... Energy should not be wasted. Water should not be wasted. Stuff should not be wasted. Things should not be wasted. Time should not be wasted.....:(
Human resources should not be wasted. If you have an employee capable of managing a group of employees it is ridiculous to have an idiot supervisor because he is your nephew's friend. You don't see this in small companies so much but corporations are full of such situations like this. I pay people for what they can do for me and my business, nothing more or less.
My first thought was food. I HATE wasting food and never did get the hang of that it's bad to overeat just to prevent waste... But seeing other people's comments I was reminded that I also hate to waste time.. I can't bear having to hang around waiting for something that's late... I always make use of that time e.g. reading or catching up on something
