Some labor unions may consider opioid overdose response and associated training as a change in work conditions or an additional duty, raising the possibility of contract renegotiation. Collective bargaining unit representatives should be consulted early in the process and given the opportunity to address personnel and occupational safety concerns. Agencies concerned about collective bargaining issues can make officer participation in overdose reversal a voluntary activity. Additionally, some union representatives conditioned their agreement on the agency’s explicit policy not to discipline officers if their agency-supplied naloxone kit is lost or stolen.
