In these days of Google, Internet, Pizza and 108, nobody wants to use their own God-given, inborn, native intelligence. Even for drafting two sentences, people turn to CiteHR. What a pathetic down-turn of knowledge and skill. How and when will people learn to sail on their own ! Pitiable state of affairs. My response may be blunt, but no harm in calling a " spade a spade "

I really want to say one thing Sir that I am not looking for any spoon feeding. I have not been sent these type of mails in my career, so I really confused in drafting it. Because, whenever i tried to do it, I was afraid that I may sound proud or arrogant in informing the others stating that I have been assigned another department. As others said it will be professional if the management sends this information to employees, but in my case I was asked by my management to inform all the employees about this change.

This is what I have drafted: Looking for advises on this...............
