You are truly an idiot. Adios.
Do you think it’s a government rule that you have to hire someone, like a law? Or is it a moral law? Do you have a Bible verse or aphorism that expresses the requirement? What’s your support that you need proof that someone is a bad worker in order not to hire them?
Calling names doesn’t do anything but raise your blood pressure and make you look like you don’t understand the basics of what you are attempting to discuss.
