Maybe you should complain about them getting in late?

Complaining about when your boss shows up to work isn't a recipe for success in any job.

Complaining might be a strong word, but I would definitely have a pithy comeback ready at the first sign of criticism, eg. "Ok, Mr. StartsAtEleven…", "early to bed, early to rise..", etc.
