We study task reorganization after technological change using worker–task-level data from a large Latin American bank. Two sequential interventions,  automation of routine transactions and a later redesign of performance evaluation, separately alter production technology and organizational design without reducing employment. Automation raises output per worker but generates only limited task reallocation: workers expand routine production rather than reallocating effort toward higher-value tasks. Task reallocation remains limited until the firm redesigns performance evaluation. After the redesign, activity shifts toward the newly prioritized task across the workforce, while gains in non-targeted complex work, and the associated wage gains, concentrate among workers with low adjustment costs, proxied by tenure. The results highlight how automation-induced task complementarities require deliberate organizational redesign, with gains shaped by the distribution of adjustment costs within the firm.
