NVC
NonViolent Communication contains 4 basic components:
[O]bservations
Objectively observing the situation - without evaluation, blame or moralistic judgement
[F]eelings
Identifying the feelings that the situation brings up
[N]eeds
Connect with the need that is not being met - you could use The 16 Basic Desires model
[R]equests
Make a request that would better meet your needs
Example
I noticed you’ve been late 3 times a week and last week (observation).
I feel anxious (feeling) because we need to meet our deadlines (need).
Do you need a few days off to sort out personal matters at home (request)?
