An interesting thought exercise for large corporations: Reverse the org chart. Put the people at the bottom in charge and people at the top do the grunt work.
There are people at the bottom that are more capable than you think. And a lot at the top that have been pulled up politically, not on merit. Expose them to the muck and bullets and they might not last long.
Conversely, if you are at the bottom, imagine you were already at the top and the org chart has just been reversed. What would you do to get back on top? What would be your priority?
