A sample for "溫柔而又堅定地說NO",

1.This is a good suggestion.I will ask xxx(your boss) if I should do it next.

Then no what matter what your boss say,This is your boss's decision,not order from your co-worker.Got it?

這可是立場問題，是屁股做在哪裏的問題，不能含糊。如果你做了同事讓做的事，而你老板不同意，老板問你：who is your boss?
你怎麽回答？

The way you thought for NO is rude.

Why? this is your job. you want me to do your job?
Nope,I am not gonna do that
