The U.S. Centers for Disease Control and Prevention (CDC) said in May that fully vaccinated people do not need to wear masks in most instances, including at work. The UAW and the automakers said temperature screening upon entering facilities is expected to be phased out.
The UAW and automakers continue to recommend autoworkers get vaccinated.
Many U.S. employers are still requiring vaccinated workers to wear masks in workplaces.
Volkswagen AG's U.S. unit said it will "no longer require masks for fully vaccinated employees after June 21, and will continue to follow CDC guidelines."
Toyota is among the automakers that has ended temperature checks and entry questionnaires at U.S. plants but it is continuing to require facial coverings.
