The California Supreme Court Monday issued a ruling Monday that expanded the number of workers that may be classified as employees and not contractors, according to the Associated Press. The suit, brought against the package delivery company Dynamex Operations West Inc. by labor unions on behalf of drivers, may affect ride-hailing giants such as Uber Technologies Inc. and rival Lyft Inc. "It makes it far more likely than before that in California, the Ubers and Lyfts will have to begin treating the workers as employees," Michael Rubin, an attorney for the drivers, told AP. The court adopted a tougher standard to determine whether a worker can be classified as a contractor. The decision is seen as a victory for labor advocates and will likely mean that more workers in California are eligible for minimum wage, rest breaks and other benefits, AP reported.
