KANSAS CITY, Mo. (AP) _ Delegates to a United Auto Workers bargaining strategy convention Tuesday killed an effort that would have required bargainers to seek cost-of-living protection for the union's 446,000 retirees.

By knocking down a procedural move to have the convention consider a resolution from a Flint, Mich., local, delegates supported UAW President Owen Bieber's plea to keep negotiating committees unfettered.

After winning the vote Bieber engineered a quick end to the convention, which originally was scheduled to conclude Wednesday, with delegates adopting dozens of resolutions directing negotiators this summer.

At a news conference later, Bieber said the union would seek inflation protection for its 446,000 retirees.

''We'll have the whole six miles out there,'' he said, meaning all options to protect the income of pensioners will be considered.

The UAW isn't required to bargain for retirees. But in the past, the union has negotiated lump-sum payments for retirees to counter inflation.

A COLA for retirees proposal could be extremely costly for the Big Three automakers, the companies and the union have said. The union estimates that such a provision could cost more than $1 billion a year for the Big Three.

Contract talks open in July with each of the Big Three.

Automakers and UAW executives alike have warned that the cost of a sliding inflation protection instead of a lump-sum payment could result in reductions in other benefits.

Despite that, the COLA for retirees issue has been gaining steam in recent months.

On Tuesday, after about an hour's debate, a move by delegate Alex Wassell to bring a resolution from Flint calling for COLA for retirees to the convention floor failed overwhelmingly in a show-of-hands vote.

During the debate, Bieber repeatedly told delegates that although a separate resolution doesn't include specific references to COLA, negotiators would bring the matter to bargaining tables at General Motors Corp., Ford Motor Co. and Chrysler Corp.

''I do not believe that there is one single person in this convention hall, and certainly your president, who reads that language to preclude our attempting to get COLA,'' Bieber said.

That wasn't good enough for Wassell of Local 1776 at GM's Willow Run, Mich., assembly plant.

''I was trying to shoehorn Bieber into getting the language,'' he said. ''I'm not satisfied because Bieber may indeed not make that a top priority.''
