Costco’s Board’s rejection of a recent shareholder proposal underscores the wastefulness of anti-DEI efforts and the value of supporting DEI.

A shareholder proposal is arguing that Costco's diversity, equity and inclusion policies are making the Issaquah-based company susceptible to legal risks.

The National Center for Public Policy Research is lobbying Costco to eliminate its DEI programs. Company leaders are not obliging.

Despite a growing list of companies abandoning DEI, one Costco board member has called for "maximizing" it in the workplace as the wholesaler grapples with a shareholder dispute.

Costco is defending its DEI practices amid calls for a boycott, offering a lesson for other brands facing similar pressure.
