Add Macy's to the list of retailers kicking off "Black Friday" on Thanksgiving Thursday. Macy's will open the doors at most of its 800 namesake department stores at 8 p.m. on Nov. 28. The company said the shift was voluntary for workers and that the move was "consistent with what many rivals are doing." Traditionally, retailers have waited until Black Friday, the day after Thanksgiving, to start their end-of-the-year push for sales. U.S. retailers have extended their hours on Black Friday in recent years to get a jump on the holiday season sales.
