具體到你這個case,我覺得至少可以采用中策:不樹敵。樹敵何益?寫拒絕的email,也沒有必要公開地羞辱一個人。
換個思路:
Joe, congrats to your promotion, well deserved. Your newly proposed projects are very exciting, I am sure they would boost the performance of our world-famous product, which is the best thing human beings ever have, and I am honored that I am picked as the executor. However, my hands are pretty tight for the time being, as you may know I am working on several important projects like reducing green gas emission, fighting against global warming and children starvation in the developing countries etc etc. I have to discuss my priorities and availability with my boss, mean while, I'd suggest you to get more resources from the top management. Any-hoo, I'd love to help in different ways before everything is sorted out, like sharing my experience and ideas...
這兒來個免責條款:隻是思路,不是語錄。上回某個帖子就被實心老鷹拍了磚。
發email,尤其是群發的時候,措辭一定要講究, being positive and cooperative. Two wrongs can't make a right.
