The Employee Assistance Program (EAP) is a confidential professional counselling service that is available to all DFES employees, volunteers and their immediate family. The EAP comprises qualified social workers and registered psychologists who can assist with personal or work related issues. Currently DFES engages one EAP provider – PeopleSense, who provide a 24/7 crisis counselling service. More information is available here.
