Sounds like you should get a new manager.

As a manager one should be extra careful to be _seen_ eating your vegetables, flossing your teeth and getting your code reviewed.

(What you do in private is a different matter. In some companies office politics can require some skullduggery.)

It was just a joke, but we're talking about a manager who "makes drive-by commits of py2-only code, months after you all agreed that all new code should be py3-compatible, and then leaves town for a multi-week vacation..."
