New York City will mandate COVID-19 vaccination for all city workers, eliminating a testing option.

Starting Wednesday, all employees who get their first shot at a city-run site will receive an extra $500 in their paycheck. The benefit will end on Oct. 29, the deadline for employees to submit proof of at least one dose, Mayor Bill de Blasio said in a statement.

Employees not vaccinated by then will be placed on unpaid leave, the mayor said. The city will immediately begin "impact bargaining” with affected unions, according to the statement.
