Wow. This article gives some information on a dispute between vendors and management at a California market that has, sadly, gone to court. The article (which certainly needs more information from both sides) and the ensuing comments show that this issue has been coming for a while in this community.
Long ago, when I was learning non-profit management, I proudly related to my supervisor at the end of the day just how I had stopped an argument between 2 senior staff while the entire staff was driving to a site. I expected congratulations, but instead my excellent boss said to me: “Well, I’m glad you stopped it, but I would expect you to have seen the argument escalating long BEFORE that point and steered the conversation and tone to other directions before it got to inflammatory words that now everyone remembers throughout their day. So, next time plan ahead and try to orchestrate good interactions from the beginning. It’s your job to give everyone the best chance to succeed at their job and that also means reducing tensions that are unnecessary.”
Good advice still.
