Dollar General expects to grow its workforce by 6% this year, adding up to 10,000 full- and part-time jobs across its stores, distribution centers and other operations. The retailer, which operates more than 18,000 US stores and plans to open 1,110 more this year, is expanding both its namesake chain and its higher-end Popshelf format, which sells most merchandise for $5 or less.
