This paper is based on research examining how supervisors within the Delta Police Department in British Columbia lead frontline police officers following exposure to traumatic events. The study finds that the role of the patrol supervisor is incredibly important in the provision of guidance and leadership to teams following traumatic events. The recommendations include the consistent enhancement of current knowledge bases, but also new initiatives to strengthen psychological support and awareness. The conclusions are applicable to other first-responder organisations and highlight the importance of supervision in post-trauma response. This work will help reduce the stigma related to mental health and create an environment of emotionally intelligent supervisors.
