From big Wall Street banks to corner grocery stores, all private employers in New York City will have to require their workers to get vaccinated against COVID-19, the mayor announced Monday in the most sweeping vaccine mandate of any state or big city in the U.S. The Greater New York Chamber of Commerce, which includes some 30,000 businesses big and small, said it supports the tightened measures. "This is for the health and public safety to keep the economy growing, to keep tourists feeling safe when they come here," Mark Jaffe, President of the Greater New York Chamber of Commerce said. "We don't want to be a headline - 'New York City is leads the nation in COVID' - we don't want to lead the nation in COVID rates, and this is an important step." But other industry groups said the plan would add to the strain on businesses still struggling to recover from the pandemic and find enough employees.
