Jamie Dimon is apologizing for using some particularly salty language about work-from-home policies, after he tackled an increasingly combative issue for workers and employers across the United States.

CEO Jamie Dimon said he regretted cursing during a recent company town hall but stands by the importance of the company’s new return-to-office policy.

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.
