An organisation is like a tree full of monkeys - all on different levels, some climbing up. 

The monkeys on top look down and see a tree full of smiling faces. The monkeys on the bottom look up and see nothing but assholes. 

Part 2 

All the time, the monkeys on the top will get the fruits first, and most of the time, they will eventually produce SHIT for all the monkeys below. 

And all the time, that's what the monkeys below will get. 

Part 3 

For those monkeys who are climbing up, they have to first kiss plenty of ass in order to move up. How high they climb will have to depend on how good they kiss. And always if the one on top will not kiss any ass, his ass will get KICKED !!! 

Part 4 

During times of great difficulties and hardship, the monkeys on the top may fall a few branches down and hit the monkeys below. The monkeys below will be fallen upon and eventually some will fall off the tree, as in retrenched. 

As compensation these monkeys that fell off get to keep the fruits that were shaken off the tree during the commotion. The tree becomes lighter and life slowly returns to normal. 

And that my friends is what we call a corporate lifecycle.
