Can the 180-day non compete clause be enforced that we all signed, no trade secrets involved.

A home health care agency in NJ has 6 nurses that attend to a pediatric case that is federally funded. The mother and father choose to leave this agency and go to another one where 2 of her 6 nurses also work. Mom and Dad have been very unhappy with the first home health agency for a while, tried to work with them but got fed up with them and went to the home health agency where the 2 nurses worked as well.
Now, the home health agency that had the case is harassing (questioning whether or not we coerced or had undue influence over the parents to go to this other agency.) One nurse did not know that mom and dad were changing agencies, the other 3 did and were going with the patient for continuity of care; however, 1 changed her mind and caused problems.
