After a year of working at home because of the coronavirus, a big chunk of workers aren't ready to head back to the office just yet. Most want assurances they will be safe in the workplace, and a large number of them say businesses should require employees to be vaccinated. Failing that, employers should offer incentives persuading workers to roll up their sleeves and get a shot, according to a March poll of U.S. workers. A separate poll shows owners of small and midsize businesses think along similar lines. "The COVID-19 vaccine is slowly starting to reach some segments of the workforce, but the road ahead remains complicated for employers — from when to bring employees back to how to ensure safety,” said Melissa Jezior, president and CEO of Arlington, Virginia-based Eagle Hill Consulting, which has surveyed workers on their attitudes about heading back to the office.
