Back in January, a dramatic development swept through the investment banking world: Bank of America Merrill Lynch and others announced a reprieve from 80-hour workweeks.

According to the New York Times, Goldman Sachs “instructed junior bankers to stay out of the office on Saturdays.” A Goldman task force recommended that analysts be able to take weekends off whenever possible. Likewise, JP Morgan Chase gave its analysts the option of taking off one protected weekend—Saturday and Sunday— each month.
