The transport wing of the Maharashtra Navnirman Sena has called for a strike of drivers of cab aggregators Uber and Ola starting midnight. The strike has been called by the Maharashtra Navnirman Vahtuk Sena which has claimed that several drivers are not being able to cover costs due to falling business. "Ola and Uber had given big assurances to the drivers, but today they are unable to cover their costs. They have invested Rs 5-7 lakh and were expecting to make Rs 1.5 lakh a month. But drivers are unable to make even half of this because of the mismanagement by these companies," Sanjay Naik of Maharashtra Navnirman Vahatuk Sena told PTI.
