ELKTON, Va. (AP) _ Workers at a Coors Brewing Co. plant here rejected the Teamsters' bid to represent them on Thursday, leaving the bulk of Coors workers non-unionized.

The workers voted 127-99 to reject the union's overture.

``Our employees were offered a choice, and they chose to continue building a partnership with management,'' Peter Coors, the company's chief executive, said from the company's headquarters in Golden, Colo. Coors had visited the plant earlier this week to encourage workers to reject the Teamsters.

The main issues were benefits and job security at the plant, where the number of full-time, temporary production workers had risen to 75. Workers were concerned that temporary workers earning $7 an hour with no benefits could replace permanent employees who earn about $16 an hour, electrician Tavares Williams said.

Coors, the nation's third-largest brewery and the only major U.S. brewer with a nonunion work force, hadn't faced a union vote since 1988. In that vote, workers at the Golden plant also rejected Teamsters representation.

The only Coors plant with union workers is a former Strohs operation purchased in Memphis, Tenn., in 1990.

In Elkton, Coors adds water to condensed beer brewed in Colorado.
