The UnitedHealthcare subsidiary Optum is carrying out widespread layoffs in the United States and hiring widely overseas, according to online reports. In April, Andrew Witty, the C.E.O. of the parent group UnitedHealth Group, “told investors the company employed 400,000 people – a figure that was down about 10% from the 440,000 listed as the year-end 2023 tally in a regulatory filing,” according to The Minnesota Star-Tribune. Job cuts in New Jersey, California and Ohio this year will total 800, the paper wrote.
