Dear Mr. Bhaskar,
I differ with your views that "the best performing employees are using the brain and making wealth (unduly) which is being tolerated by the management upto some extent." The fact is totally on the reverse side. The best perforning employees never think about their involvement in frauds or corruption, as they don't find any time even to remotely think about that due to their full concentration on their performance only. Rather, you will find that the best performing employees are neither compensated adequately for their performance, nor they are made so close by their bosses to know about their secrets. It is only the wicked brain employees, who just think nothing except about making wealth by hook or crook and don't bother on their performance except to please or grease their bosses, or merely the touting employees who are never the best performers but think just on making wealth either due to their being very close to the top management, which closes eyes even on reporting against those employees, or some of the top bosses even use them to make corruption on their behalf also keeping themselves in disguise.
The reason behind organisations not taking any stringent action against the erring personnel in their organisation is not the best performing employees, BUT, the involvement of a few of the top bosses, themselves, in the corruption. No honest management spares even the best performing employee when the question comes to corruption and fraud on his part. I can bet that in the black money cases, you won't be able to find even a single account of any best performing employees in any Swiss bank or any other foreign country account. On the contrary, you would find the accounts of politicians, top bureaucrats or the business tycoons, who believe in giving and taking bribery. IT IS MERELY THE MISCONCEPTION OF YOUR MIND.
I wonder, what made you think about the best performing employees using their brains to make wealth (unduly)?
