what goes around, comes around

In the corporate world, professionalism is a descriptive important for Best Practice. How do we define professionalism?
For starters, in the application of a rule, it works across the board, not by personal preferances or emotional comfort zones with immunity for the preferred.
When does a person cease to become a professional?
When the person crosses the line between business and personal friendships.
In small business set-ups, most would be able to 'look the other way' when such tiresome situations occur. But in huge corporations, it's sinful for the majority who toil and tow the corporate line.
BUT being a small fish in a big pond, we could simply swim away and go to another part of the tank, where we are more comfortable, playing with other guppies. Why go venture with Lou Han when all he ever thinks about is having you for dinner?
Since there is nothing proactive that can be done to make the waters safer for the majority of us guppies, we ought to just wait for his greed to take the better of him - he could visualise a net scooping down the pond and have hopes of living in a larger pond - when in actual fact, he was going to a 2-feet fish tank in someones aquarium shop!
There is such a thing as the Circle of Life - and life is fair - it just has some wait states....
