For the first time in its 155-year history, Macy's is doing what others do and staying open late on Thanksgiving, which makes one pity employees. Stores will open at 8 p.m. on the holiday, four hours earlier than in previous years, the company said Monday. "Black Friday is the biggest shopping event of the year and brings with it a level of fun and excitement to our customers around the nation," Peter Sachse, Macy's chief stores officer, said in a news release.
