I go one further
I use my phone to secretly record everything said in meetings. You never know when it could come in useful. Obviously you can't ever tell anyone you do it as I'm sure they'd go nuts over it and HR would show you the door.
Used to use it with every meeting called into at old place of work as they were back stabbing fucks in senior management. If I ever do it now, it is purely for notes as I actually respect and trust people in the new place of employment.
