Illinois has adopted the Biden administration’s vaccine-or-test requirement for private employers, according to new rules announced by state authorities on Jan. 7, the same day the Supreme Court heard arguments challenging the federal mandate.
The Illinois Department of Labor (DOL) said in an announcement that it had filed rules adopting the federal Occupational Health and Safety Administration (OSHA) COVID-19 Emergency Temporary Standard, which imposes a vaccination requirement with a test-out option on private companies employing 100 or more people.
