Ask any manager this question, "Your company's revenues reduce by 20% per annum over two years. What would you do?"
Or this one, "You have an employee who hasn't delivered on his potential, and clearly is not worth the money you are paying him. What would you do?"
I'm quite willing to bet that nine times out of ten, the answer would be along the lines of asking people to leave (may or may not be couched in a euphemism like downsizing, right-sizing, "let go of", "not carry baggage", etc.)
Then ask them this one, "You have an employee who has been a star performer. You have rewarded him over the years, and he has performed. Now he wants to quit as he feels this company is too small for him, or not fulfilling his career aspirations, or not paying him enough. How do you feel about that?"
I'm equally certain that the feelings expressed will be that of outrage, of being cheated, of (the employee's) disloyalty, of how today's employees just don't care enough about the company, etc.
All i can say in response is "Grow up! guys!!!"
