The code of silence is acting negatively for the CAF at this point, not perhaps positively as it was intended. I would recommend doing exit interviews or exit surveys with CAF members who are exiting out of basic training all the way to CAF members who are exiting after 20 years in the service. Within that survey, I would try to break down that code of silence by asking specific questions: Did you feel supported from a medical standpoint? Where you matched with a medical professional? Did you have child care?
Make these surveys and interviews easy to complete and also try to make them as mandatory as possible.
