Shadow work as pump gasoline, bag groceries, make travel arrangements, and check baggage at the airport. He includes the rise of technology and robotics as forces leading to the growth of shadow work, and also includes such factors as crowdsourcing and parental over-engagement in their children's' lives. He argues that downloading of tasks to consumers takes away from their time and reduces the amount of casual social interaction in peoples' lives. It also limits the number of opportunities for low skilled entry level work (such as pumping gas). Shadow work In economics, shadow work refers to unpaid labor in the form of
Work (thermodynamics) system is well defined and equal to the pressure exerted by the system on the surroundings. This arrangement for transfer of energy as work can be varied in a particular way that depends on the strictly mechanical nature of pressure–volume work. The variation consists in letting the coupling between the system and surroundings be through a rigid rod that links pistons of different areas for the system and surroundings. Then for a given amount of work transferred, the exchange of volumes involves different pressures, inversely with the piston areas, for mechanical equilibrium. This cannot be done for the transfer of
