Mars Hill Church to Former Employees: Don't Talk

According to a brief report at last night, Mars Hill Church and Elevation Church (NC) require staff to sign non-disclosure agreements. Warren Cole Smith has seen one and indicates that it even covers the employee’s spouse. Former elder Dave Kraft said the agreement was like “a gag order.”
I have heard former MHC people talk about these agreements but they were afraid to talk on the record because they feared being sued by their former church. Mars Hill watchers: Has anyone ever been sued over a perceived violation? It seems hard to believe that a Christian church would actually sue someone over discussing factual matters during employment.
