- When approaching someone about behavior youd like to see changed, stick to factual descriptions of what theyve done thats upset you, rather than labels or judgments.
Heres an example:Situation:
Your friend, who habitually arrives late for your plans, has shown up twenty minutes late for a lunch date.Inappropriate: "Youre so rude! Youre always late."
Assertive Communication: "We were supposed to meet at 11:30, but now its 11:50." - The same should be done if describing the effects of their behavior. Dont exaggerate, label or judge; just describe:
Inappropriate: Now lunch is ruined.
Assertive Communication: Now I have less time to spend lunching because I still need to be back to work by 1pm. - Use I Messages. Simply put, if you start a sentence off with You, it comes off as more of a judgment or attack, and puts people on the defensive. If you start with I, the focus is more on how you are feeling and how you are affected by their behavior. Also, it shows more ownership of your reactions, and less blame.
For example:You Message: You need to stop that!
I Message: Id like it if youd stop that. - Heres a great formula that puts it all together:
When you [their behavior], I feel [your feelings].
When used with factual statements, rather than judgments or labels, this formula provides a direct, non-attacking, more responsible way of letting people know how their behavior affects you. For example:
When you yell, I feel attacked.
- A more advanced variation of this formula includes the results of their behavior (again, put into factual terms), and looks like this:
When you [their behavior], then [results of their behavior], and I feel [how you feel].
Here are some examples:
When you arrive late, I have to wait, and I feel frustrated.
When you tell the kids they can do something that Ive already forbidden, some of my authority as a parent is taken away, and I feel undermined.
- Make sure your body reflects confidence: stand up straight, look people in the eye, and relax.
- Use a firm, but pleasant, tone.
- Dont assume you know what the other persons motives are, especially if you think theyre negative.
- When in a discussion, dont forget to listen and ask questions! Its important to understand the other persons point of view as well.
- Try to think win-win: see if you can find a compromise or a way for you both get your needs met.
