Dear Minh-Hanh, As a executive director of a labor-management council and as an ordained United Church of Christ minister I was interested in your question. In our work with labor and management groups we use the "Getting To Yes" 7 Elements - Conflict Resolution and Collaboration process developed by Roger Fisher of Harvard Law School. We also use OST. Both are effective. So, to answer your question, the answer is yes.
Let me also mention something else as an FYI. In April, we will have an OST event with our public housing authority (PHA) on April 15th and 16th. What will be interesting is that we have trained most of the PHA staff in the 7 Elements - Conflict Resolution process. What I am waiting to see is if we can combine the skills people have through the 7 Elements, with the format of OST and have even a better result, especially as it relates to the quality of the small group sessions. I will pass on results to the OSTLIST. Also, I will be attending the OST event in Chicago the following week. Thanks, Dave Koehler
