Lightswitch Shift: A unit of measurement for how long your workday is, defined as at least 14 hours. The terminology comes from buildings in the Redmond campus which use energy saving features whereby office lights will automatically go off between 9pm and 7am. A lightswitch shift refers to an employee that started the work day before 7am and stays past 9pm because during that time employees must go outside their office and hit a main lightswitch to re-enable their office lights to turn on and stay on in increments of two hours.
