My boss told me to decrease an amount of NO during Christmas time
You can think of alternative ways of saying the same: “perhaps not”, “i think otherwise”, “come up with something different”, “maybe another time”, “we are looking into another direction”, “you would be right if you were right” (but you are not), “i agree but its not that simple”, “you know, thats an excellent idea, except that you are incredibly wrong”, “im glad to inform you that this will never happen :)”, “should i bother with the answer?”, “so ironic, you are funny”, etc

I like these variants, but they are not so ideal as NO, NO is simple and concisely, in other words, it’s perfect.
