I'm not, but I manage an engineer who recently asked. He's fantastic, why would I care? I just filled out a form with HR and he's now at 80% pay 4 days a week.

I treat him with respect and he treats me with respect. If it ends up turning into a really difficult situation for the team, we might have a discussion about how to improve. But honestly knowing he's out every Friday will probably be a good forcing function for us to have a day with few meetings etc.
