General Motors, Ford Motor and Fiat Chrysler - said last week they planned to restart production at North American plants on May 18.

Factory workers began returning to assembly lines in Michigan on Monday, paving the way to reopen the U.S. auto sector but stoking fears of a second wave of coronavirus infections as strict lockdowns are eased across the country.

With millions of Americans out of work and much of the economy at a virtual standstill, a growing number of states are relaxing tough restrictions on commerce and social life put in place to slow the outbreak.Some auto suppliers in Michigan, a Midwest industrial powerhouse hard hit by the pandemic and its economic fallout, reopened plants on Monday with skeleton crews to get ready for a resumption of vehicle production next week.

Skilled-trades workers and salaried employees also began returning to auto assembly plants to prepare for the wider restart."We're starting up our foundry this week in anticipation of the orders coming in next week," Joe Perkins, chief executive of Busche Performance Group, an engineering, casting and machining firm, said in a telephone interview.

Factory workers will be issued face masks, checked for fever and required to submit health-screening questionnaires."All of that's ready to go," Perkins said. "The big question is are people going to be buying cars and trucks."
