United Airlines will send layoff warnings to 36,000 employees - nearly half its U.S. staff - in the clearest signal yet of how deeply the virus outbreak is hurting the airline industry. United officials said Wednesday, July 8 that they still hope to limit the number of layoffs by offering early retirement, but they have to send notices this month to comply with a law requiring that workers get 60 days’ notice ahead of mass job cuts.
