Historically when CUPW has been on strike, we have entered into picket protocols to allow members of UPCE/PSAC, other unions in postal facilities, and workers such as cleaners and cafeteria staff to go to work. However, these protocols do not cover supervisors, management and other senior-level Canada Post staff. This time around, the signed protocol does not cover members in the Canadian Postmasters and Assistants Association (CPAA) bargaining unit. They have refused to sign a protocol with CUPW.
