Right on cue, the New York Taxi Workers Alliance has now launched into its second strike in as many months, with its concerns over GPS units in its drivers’ cabs still unresolved. According to the AP, Taxi Workers Alliance executive director Bhairavi Desai says that 75% of all of its drivers (representing a fifth of the city’s total drivers) were on strike, although it’s apparently not entirely clear how many drivers are actually honoring the strike. As before, the main point of contention is the GPS units that drivers are being required to used, which the cabbies say represent an invasion of privacy and work “erratically at best.” From the looks of it, there’s no indication as to how long this latest strike might last, although the last one ran for 48 hours.
