President Biden is set to meet on Wednesday with top executives from Microsoft, the Walt Disney Company, Kaiser Permanente and other companies that have endorsed vaccine mandates, days after he announced a federal effort to require employees of large companies to be vaccinated against the coronavirus or be tested regularly.

The meeting will highlight Mr. Biden’s argument that vaccine mandates are good for the economy, a White House official said, while spotlighting employers that have mandates for workers or have praised Mr. Biden’s order. The official said the meeting was meant to rally more business support for mandates.

One of the invitees to the meeting, Tim Boyle, the chief executive of Columbia Sportswear, said in an interview on Wednesday that his company had drafted a policy mandating vaccines months ago. But it had held off carrying it out until Mr. Biden announced last week that he was directing the Labor Department to issue an emergency safety declaration that would effectively function as a vaccine mandate for tens of millions of workers. Columbia Sportswear told its workers that it will put a vaccine requirement in place next week.

Mr. Boyle said Columbia was concerned that by acting alone it would risk losing as many as half of its workers in distribution centers and retail stores. Mr. Biden’s order, he said, reduced the risk that workers who don’t want to get vaccinated would quit to work elsewhere.

“There’s much less opportunity for people to go somewhere they don’t need to be vaccinated,” he said.

Mr. Boyle said vaccinations had divided Columbia’s work force. Managers in its Portland, Ore., headquarters have largely embraced the shots, he said, but retail and warehouse workers throughout the country have been more reluctant. He said that hesitancy had hurt the company, with infections and the threat of infection forcing closures and cleanings of locations.

“Those operations are predicated on people working together closely,” he said. Having unvaccinated workers is “highly disruptive.”

Several of the companies set to meet with Mr. Biden have installed mandates already, for at least part of their work force, including Disney, Walgreens and Children’s Hospital of Philadelphia.
