Indoor mask mandates could wreck NYC’s post-Labor Day recovery, group warns

A new indoor-mask mandate proposed by the CDC would undercut efforts to draw employees back to offices after Labor Day — a crucial step needed to prop up the struggling commercial real estate market and to protect the city’s economy, according to an influential business advocacy group.

Although Gov. Andrew Cuomo has not yet mandated indoor masking as the Centers for Disease Control and Prevention recommends, he said municipalities in “high-risk” areas — which include New York City under CDC guidelines — should “seriously consider it” and that he’s “studying” the proposal. Mayor Bill de Blasio said he’ll announce his masking decision on Monday. Kathryn Wylde, president of the Partnership for New York City, ominously told The Post, “Mask mandates will reverse the momentum for bringing people back to the office.” She forecast at the end of June that 62 percent of office workers would return in September for at least three days a week.
