An effective NO means — the person you are saying NO to hears the spoken information and responds respectfully.
- (I spent almost an hour coaching a middle age woman on how to respond to an abusive supervisor. She knew how to respond in a passive way (ineffective) while really wanting to respond in an aggressive way (didn’t want to get fired). She was going to quit her job that gave her family medical benefits until I taught her what to say, the proper body language and proper vocal tone. She went to her work place and taught the other ladies. They almost wanted the supervisor to go off on one of them because they knew how to handle the situation.)
say NO nicely, calmly and respectfully
while maintaining their cool factor
