CEO Jamie Dimon on Monday expressed regret about the expletives he used during a recent employee town hall, but he didn’t back down from his core message that employees need to return to the workplace five days a week.

A JPMorgan Chase executive told thousands of employees he wanted “more hustle” days after the bank’s CEO Jamie Dimon scorned staff pushback against its five-day return-to-office policy. The memo illustrates the tension between JPMorgan’s emphasis on in-office culture and employees who cite its strong performance while flexible working policies were in place.
