I often skip meetings without agenda. If they don't care to prepare a reasonable invitation, I don't care to join. Also - I skip meetings where they announce stuff. Announcements should go to my inbox, so I can read them when ready, not when they think it's suitable for them.
Some meetings dip into negative productivity.
100%. I try to keep working through them and only participate when my name is called.
