A vaccinate mandate for teachers and other school staff members in New York City took effect on Monday. It is one of the first school district mandates in the US requiring employees to be inoculated against the coronavirus. As of Monday morning, United Federation of Teachers president Michael Mulgrew said 97 per cent of his members had received at least one vaccine dose. Mayor Bill de Blasio gave a final warning to the city’s roughly 148,000 public school staffers on Friday saying unvaccinated employees would be placed on unpaid leave and not be allowed to work. The city planned to bring in substitutes where needed. New York City is not offering a remote teaching/learning option this year. The vaccination mandate allows for medical and religious exemptions. A group of teachers and other school employees who had sued over the school vaccine mandate asked the U.S. Supreme Court on Thursday for an emergency injunction blocking its implementation. The request was denied on Friday.
