Fred's friend Barney was recently wrongly fired from his job. Barney finally decides to sue his employer for wrongful discharge. Before the case gets to trial his boss apologizes and asks him to return to work with back-pay and a raise. Barney agrees. On the first day back on the job, Barney hears about a new law from a co-worker. The law apparently requires that everyone on the worksite wash their hands prior to returning to work or be subjected to a $50 fine. Barney has an aversion to washing his hands in public bathrooms, and doesn't much like the idea of paying the fine either.

Which of the following is TRUE?

Unfortunately for Fred he is once again turned away practically at the courthouse steps. Why?
