As a business owner, I learned early on never to hire someone if your rights are forfeit; I saw what happened to those who hired 'brothers' and then got taken, only to be told they could not sue.
How about this:
I fired an inlaw who was overbilling me for hours; I contested that she got unemployment, and had the proof that she was using my time and resources for private use, including looking for other jobs, on my time.
She told the elders I was taking her to court! One of her many lies.
I learned to never hire a witness for anything; it isn't that they are necessarily worse, but you give up your right to redress, if you sue them you get in trouble with the elders.
Never hire a witness if you are a witness yourself.
