Morgan in Tallahassee

Recently a day care worker in Tallahassee, Florida, took action to protect children in her care when she noticed a man in a parked van taking photos of the children outside. In response, she took the children inside and locked the gate. The response from her management and the parents was not supportive of her actions. How do we, as Alert Adults, take the actions necessary to protect children without raising the ire of other adults in the environment?
