Interest Based Bargaining Timeline. After August 15 each year PUSD and PCEA will identify mutual items for discussion in Interest Based Bargaining during the year. These items will be sunshined by the Board of Trustees and PCEA. Interest Based Bargaining meetings will be held twice a month from September through December to work on contractual issues with the goal of having a package to the Board of Trustees and PCEA membership prior to January 1 for ratification. The IBB team receives committee reports one time per month and meets one time per month from January through May.
