IT Bargaining Dispute Resolution Choice?

As far as i understand, the union decides at the start of each bargaining round, what the dispute resolution will be. The dispute resolution can be conciliation/strike or binding arbitration.

For the last PIPSC IT CA bargaining, they chose binding arbitration.

Has a dispute resolution been chosen for this round of bargaining? Do union members vote on it, or is it just chosen by the bargaining team?
