Once, someone that thought I was some sort of boss asked if it was ok to skip an all hands meeting that was advertised as an in-person required meeting. The reason? They needed to pick up their kids at school.
Of course it’s ok. Always. Never, ever be afraid to skip a meeting to go pick up your kids. Or have dinner with your spouse. Or just go have a beer with good friends you haven’t seen in a while.
Trust me: the meeting could have been an email.
