In my organization as an HR professional, I am facing an issue where one of our Board of Directors is sending very rude emails without any apparent reason. His behavior on the floor is also consistently rude. Over the past 1.5 years, there has been no attrition in our company. However, due to his behavior, attrition has started, and I am unsure of how to directly address this with him. I have approached other BODs, but they are also unwilling to take any action. Can anyone offer guidance on how I should approach this situation? Additionally, could someone please share an HR plan for the floor?
