If you’ve read Barbara Ehrenreich’s Nickel and Dimed, it’ll be pretty obvious why Walmart’s continued quest for efficiency is bad for employees and workers. The latest example? High-tech scheduling software designed to dynamically tune employee schedules to meet real-time fluctuations in the number of customers. The result will be low wage workers on-call to meet customer surges and the possibility of being asked to go home during lulls. This will make paychecks even less stable. Add to that, dynamic checks on whether an employee is reaching full-time status or overtime so that their schedule can be scaled back, and you have the makings of an increasingly unfair workplace – regardless of value of the minimum wage.
