The percentage of U.S. workers saying their employer is requiring its employees to get vaccinated against COVID-19 has doubled in the past month. Nineteen percent of U.S. employees now say their employer has such a policy in order for them to return to the workplace, compared with 9% in the prior survey from July, and 6% or less before that. Fifty-five percent of employees, down from 62% in July, say their employer is encouraging but not requiring vaccinations, while 26% say their employer has not done either.
