Enterprise AI-agent cases report burdens including customer-support answers outside scope, frequent task switching and increased code review. A BCG survey cited in the reporting found the share of organizations integrating agents into workflows rose from 13% the previous year to 30%, but that does not mean employee time fell proportionately. A survey of 1,488 US workers also examined an association between excessive supervision and mental fatigue. These cases suggest including role redesign, exception management and final human review in operating costs; they are not experiments proving a universal productivity decline.
