No no no...Go in with an "you're a bunch of pedantic morons and this is a waste of time" attitude and call their bluff. "Sack me if you dare".
Honestly, it's a great feeling. Yes I got sacked but what I did was arguably a lot worse![]()
The trouble is to these people it won't seem like a waste of time, it will be a perfect opportunity for them to justify their positions.
