UBS has instructed its employees to work from the office on either a Friday or a Monday, prohibiting working from home on consecutive days.The requirement applies to all 115,000 UBS employees and is intended to maintain productivity, innovation, and collaboration.Earlier this year, JP Morgan mandated a full-time return to the office for its employees, while UBS is opting for a more flexible approach.The Swiss investment bank's decision aligns with the trend of balancing remote work and office presence in the financial industry.
