I am not saying that the article is bad. Its good. It should be followed. But it smells of too much sincerity. The truth is that I met a large number of people before leaving Infy about a year ago. The problem with most of them was that they were too sincere, too law abiding. I am not saying one should not be sincere or law abiding but then there are times when every corporation promulgates ridiculuous rules. Being blindingly sincere curbs our propensity of opposing such rules and adversely affects the faculty of creativity. Such people keep toeing the line they are asked to as they are blinded by the shiny facade which says that everything their seniors say, is right and everything they do, a shiny example for the juniors. This idea is crap for the one thing worth nurturing is personal creativity.
Coming to this article, its good to be sincere and honest and polite and professional but only if your employer has been just and considerate of your abilities. Otherwise, they do not deserve such a nice treatment. There is only so far someone should go quietly.
