Agree and it’s also not purely “personal” when it’s with an employee. Now it’s crossed into “professional” which becomes the problem.
These things are never good for the workforce and create risks for the enterprise. That’s why most have rules against this - especially with certain org chart dynamics.
There is also the character issue which I think is more than fair for an employer to consider in such situation (e.g. leader of young adults, public figure, face of your program, etc)
This is no longer about football - it’s about black eye for Michigan.
