This from the WSJ:

One of Wall Street’s biggest employers is calling its trading staff back to the office.

JPMorgan Chase JPM -0.42% & Co. executives told senior employees of the bank’s giant sales and trading operation that they and their teams must return to the office by Sept. 21, according to people familiar with the matter.

Trading chief Troy Rohrbaugh and Marc Badrichani, the bank’s global head of sales and research, delivered the message in conference calls Wednesday morning, the people said. The two executives said employees with child-care issues and medical conditions that make them more vulnerable to coronavirus complications can continue working from home, the people added.

Like most New York City office workers, Wall Street traders and bankers scattered to the winds when coronavirus shut down the city in March. Workers began trickling back into their skyscrapers in June, when the city began reopening, but financial firms largely haven’t ordered employees to return en masse.
JP Morgan is one of our biggest (by revenue) customers. At the early stages of this disaster we were making and installing "wellness screens" between trader desks, but as it continued on they began sending everyone home. They have offices all over mid-town Manhattan, including many many floors in the Empire State Building.

This move will encourage others to follow their lead
