When we are transparent about our concerns, brainstorm solutions together, and look towards making a decision with the other person, we can increase understanding, partnership, and mutual support. This invites people to work on the same issue from the same direction, collaboratively seek solutions, and tap a deeper wisdom. In the end, the future survival of our species depends on this kind of active interdependence.
Based on your observations of "power with" interactions choose a specific, do-able to practice so that you're prepared the next time you're in a power under/power over dynamic. Keep the practice simple to do in a difficult moment. Then reflect: identify what you did (internally or externally) or said that (de)escalated the dynamic. This practice requires noticing what went well, self compassion, perseverance, and support.
