re: Firing someone...

Been there....firing someone sucks. The first person I had to let go was a single mom and the child had a disability. She was not cut out for the job in any form, shape or fashion.....really sweet, but just horrible at the job. It was REALLY tough to do regardless. Didn't sleep for nights.

Where I live it is NOT a "right to work" state.

If you are not in a "right to work" state, I don't believe any documentation of deficiency is required. You can simply say, "I'm sorry, but this isn't working out." To my knowledge nothing else is required other than paying a small bump in your unemployment rate. You can probably find yourself in more trouble trying to explain your reasoning than if you just cut ties without a specific reason.
