What can employers do if workers avoid COVID-19 vaccines? They can require vaccination and fire employees who don't comply, or take other actions such as withholding company perks or charging extra for health insurance. Businesses for months have been encouraging workers to get vaccinated, in some cases offering incentives like time off or gift cards. But more are taking a harder stance and requiring vaccinations for any remaining holdouts, a push that has gained momentum since Pfizer’s vaccine recently received full approval from the U.S. Food and Drug Administration.
