Many people fear that word “negotiate.” Because it means “someone trying to take something from me and me trying to keep that from happening.”
That’s not negotiation!
Negotiation is more like two people finding value by exploring the said and unsaid needs and values of each other and chipping away at discovering each other until boom! Mutual value.
So “renegotiating” is an adjustment of mutual value, not a taking. It should be a delight to have someone you value ask for a renegotiation and something you should ask for when the current arrangement isn’t working for you!
