For decades, junior bankers and Wall Street firms had an unspoken pact: in exchange for reasonably high-paying jobs and a shot at obscene wealth, young analysts agreed to work fifteen hours a day, and forgo anything resembling a normal life. But things may be changing. Last October, Goldman Sachs told its junior investment-banking analysts not to work on Saturdays, and it has said that all analysts, on average, should be working no more than seventy to seventy-five hours a week. A couple of weeks ago, Bank of America Merrill Lynch said that analysts are expected to have four weekend days off a month. And, last week, Credit Suisse told its analysts that they should not be in the office on Saturdays.
