“An American Management Association survey found that 66 percent of US-based employers monitor the Internet use of their employees, 45 percent track employee keystrokes, and 43 percent monitor employee e-mail. UPS uses a system, Kronos, under which each of its delivery trucks is equipped with 200 sensors, which feed information back to headquarters about driving speed, seatbelt use, and delivery efficiency. Even trying to cheat the system can hurt the worker. Drivers commonly evade the seatbelt sensor by keeping the seatbelt locked but not strapping themselves in. UPS can claim higher safety compliance even though workers are actually more endangered.”
