May Purdue prohibit an employee from coming to work if the employee is known to have contracted COVID-19 themselves, or to have had close contact with someone who has? (Updated June 29)

Yes. Purdue is obligated to provide a safe workplace and may take necessary and reasonable steps to minimize health risks for its employees, such as requiring that employees not come to work if they have or have been exposed to COVID-19. Employees in this situation should contact Protect Purdue Health Center 765-496-INFO (4636) or 833-571-1043 (toll free) for assessment and guidance on testing, treatment and returning to work.
