A banked hours scheme (banco de horas) is a flexible working time arrangement under Portuguese labor law that allows employees to accumulate overtime hours and use them later as time off, rather than receiving immediate overtime pay.

Under the Portuguese Labour Code, banked hours can be established through collective agreements or, in some cases, individual agreements. The scheme allows employers to vary working hours based on demand — requiring longer hours during peak periods and compensating with shorter hours or days off later.

Banked hours schemes are a frequent topic in labor reform negotiations, with unions (particularly CGTP) pushing for tighter limits and greater worker protections, while employers argue for more flexibility. Proposed reforms have included extending eligibility to parents of young children and adjusting the cap on banked hours.
