Is a grievor's bargaining agent entitled to withdraw a grievance?

43 Furthermore, a grievor must cooperate with the bargaining agent in the individual grievance process. A bargaining agent cannot represent a grievor in the absence of his or her cooperation. Failing to cooperate with the bargaining agent, which results in the bargaining agent’s inability to productively work with the grievor, means that the bargaining agent may be entitled to withdraw the grievance (see Mississauga (City), [2006] O.L.R.D. No. 2421 at para. 39). Grievors must take all necessary measures to protect their interests and cooperate with their bargaining agents (see Ouellet v. Luce St-Georges and Public Service Alliance of Canada, 2009 PSLRB 107 (CanLII) at para. 32).
