Laborers Local 663

What Laborers Local 663 does

Laborers' Local 663 is a construction craft labor union chartered in 1938 and affiliated with the Laborers' International Union of North America (LIUNA). The union represents thousands of construction laborers across Missouri and Kansas, operating from a headquarters union hall in Kansas City, Missouri (7820 Prospect) and a branch office in Springfield, Missouri (1700 S. Campbell), supported by a 12-person staff. Its core purpose is collective bargaining on behalf of construction workers in heavy construction, building construction, and general labor categories, with active multi-year agreements covering more than 60 Missouri counties across four contractor-association counterparts.

The union's product surface is built around member services rather than commercial offerings: a member portal for online dues payment, a referral application funnel for prospective members, an online merchandise store, and a public labor agreements directory listing wage rates and contract details. Apprenticeship and skills training are delivered through affiliated training centers (GKC Training Center, Belton Training Center, MokanLTC), and fringe benefits administration is handled in partnership with CIL Funds.

The business model is a recurring membership dues structure funded by working construction laborers, supplemented by dues-related remittances through participating contractors. Distribution relies on community presence and referral applications in Missouri and Kansas, monthly in-person membership meetings at both union halls, contractor-association relationships that govern work access, and the online member portal for dues and communications. Governance is provided by elected officers — President & Business Manager Jason Mendenhall, Vice President Phillip Butler, and Secretary-Treasurer Gabe Jones — alongside business agents and office managers in each location.
