Tuesday Morning, the Dallas-based discount chain, is the latest national retailer to file Chapter 11 bankruptcy. The company blames coronavirus for its cash-flow problems, but says it expects stay in business after a reorganization. Several hundred Tuesday Morning stores will be closing permanently, including locations in Glen Burnie, Salisbury and Towson. But the retailer already has reopened in Rockville, where its mix of home goods and snacks is apparently considered an “essential” business.
