Participation

You participate in this plan if you work for an employer signatory to a collective bargaining agreement or a written contribution agreement recognized by the Board of Trustees. Signatory employers are required to make an hourly contribution to this plan for each covered hour you work. The hourly contribution amount can change from year to year as determined by the collective bargaining agreement (please see Introduction and Employer Contributions). Most collective bargaining agreements also allow 401(a) supplemental contributions to this plan (please see 401(a) Supplemental Contributions).
