I work for a "Right to Work" company. I manage 36 employees. Even though we are RTW, I must have clear documented evidence of why I want to let someone go before HR will even think about acting. The potential lawsuit is just too costly. It is true that I can let someone go without cause, but that does not stop the potential lawsuit. Companies will settle before they litigate and the settlement is generally $35k. So, the first thing they ask me, "do you have clear documentation of all offenses and corrective actions?" And after that, "do you have supporting evidence from other employees?"
