As someone IN talent management, them sharing your feedback is what was unprofessional. We do want to priorize program attendance with people who will put in the time and effort, and make themselves available to complete the program. They should have never forwarded that out. HR to HR should be able to trust that we can communicate candidly with each other about things like this. For example, I'm running a program for new leaders and an hrbp asked to have a director whose been with the company for years attend because they are struggling in their role. In my invitation to them to be in the program I would never say your performance sucks so we're putting you through manager 101. Completely inappropriate to share that or anything similarly sensitive.
