I'd be surprised if the boss lies under oath. He's going to have to explain what the word "bonus" means and it doesn't sound like it's regular pay or overtime.

Oh, well...we shall see who lies under oath. I would dearly love to be a fly on that wall when this happens.

Sit quietly, the answers will reveal themselves when you least expect them to.
The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
