Many businesses have, so far, decided on a lighter touch. As they reopen offices, they have strongly encouraged employees to get vaccinated but stopped short of requiring it. That includes Amazon, which offers front-line employees as much as $80 to be immunized, and Walmart, which provides shots at its stores and gives associates two hours of paid time off to get theirs. A recent survey by the consulting firm Mercer Total Health Management found that 73% of employers don’t plan to make vaccination a requirement... “People don’t want to go into something that feels like an antagonistic relationship in their workforce,” said Mary Kay O’Neill, senior clinical adviser for Mercer. “Employers are just trying to be supportive and facilitative of getting the vaccine without it being a rule.”... Many universities already require student vaccinations for other diseases. They say they’re on firm footing to mandate coronavirus vaccines, said Emily Morgese, a vice president of the Commission on Independent Colleges and Universities in New York, a group for administrators. Implementation, however, can be tricky, particularly for schools with large international populations.
