How would a nursing agency stop their employees from doing side jobs with a client at a discounted rate? For example, lets say you hire Sandy who is a CNA and pay her $10/hr. She is assigned to work with John, Jim and Jose who pays your company $15/hr each. Sandy, being the greedy person she is, decided to tell the three clients that she would eliminate the middleman and work at $13/hr. She gets paid more, they pay less, you get nothing.

It seems like almost any CNA can build a list of clients and then side step the agency and do it on their own. What kind of preventative measures are taken against this?

Thanks.
