CHICAGO, Dec 6 (Reuters) - Tyson Foods (TSN.N) said on Monday it will pay about $50 million in year-end bonuses to frontline and hourly meatpacking workers starting this month, as companies compete to attract and retain employees. The one-time bonuses for 86,000 eligible Tyson employees will be based on tenure and range from $300 to $700, the company said. U.S. meat processors have struggled to find enough workers this year due to the tight labor market and safety concerns during the COVID-19 pandemic. About 59,000 workers were infected with the COVID-19 through January at plants run by Tyson and competitors JBS USA (JBS.UL), Cargill Inc (CARG.UL), National Beef Packing Company (NBEEF.UL) and WH Group"s (0288.HK) Smithfield Foods (SFII.UL), according to a U.S. House of Representatives subcommittee report. read moreThe meatpacking industry was especially hard hit by the pandemic in part because its workers tend to be in close quarters for long hours.
