Manager taking long lunches!! (US) There is this manager with no direct reports who takes daily 2 hour lunches. We're all pretty irritated by this since we have to be here for a full 8 hours and he only has to work 6. We all talk about it but no one wants to be the one to blow the whistle (middle management has a tendency of sticking together). I was thinking to send an email from a throwaway account to our HR &amp; cc his manager reporting the issue. Is this a bad/petty idea?

We're just all so frustrated!
