“We’re still trying to figure out how to do it,” Mulgrew said. “It’s not easy to figure out three feet in a classroom and six feet everywhere else in the building.”

If we had a political class with even the semblance of a backbone, our leaders might have responded: “What the hell are you talking about?” and maybe added: “Get back to work or get fired.”

Why would kids need to be six feet apart elsewhere in the building when researchers have established that three feet suffice? Mulgrew added that his union listens to its own, independent doctors, not the CDC. How nice for them: Can the rest of us also take advice from independent doctors?

The anti-science union has been at the forefront of ruining schooling in the Big Apple, far beyond the distancing rules. It was the ­union, after all, that extracted a moronic 3-percent-positivity trigger for shuttering schools — ­including in Manhattan, where the healthy and wealthy love to test frequently.
