Public legal education groups, including the Justice Education Society, in British Columbia have created online guides to help a person have difficult conversations.
They are particularly meant to resolve disputes before they become more problematic.
These give a small training in the mindsets and approaches a person can use to get to better outcomes. It’s not just the step-by-step of the process, it’s about changing lenses & strategies.
For example, here is the Negotiating a Solution resource. It provides overarching frameworks, priorities, and tips.
How to deal with ‘tough talks’ is available here at their site.
