Challenges and Conflicts: A Global Overview

Former Hudson's Bay workers are putting their faith in Ruby Liu. The B-C billionaire is on a hiring spree - hoping to attract workers for her own stores at former Hudson's Bay locations. The catch? The stores haven't opened - and Liu hasn't even leased out the buildings.

Plus: Dozens injured in L.A. car ramming, India's judicial backlog, Japan's upper house election, and more.
