ARI SHAPIRO, HOST:
Good morning, I'm Ari Shapiro. Wal-Mart is trying to change its cold corporate image, literally. Workers complain of freezing on the job. Yesterday, Wal-Mart executives told thousands of employees that the stores will be warmer. Workers also complained that they are bombarded by a constant assault from Celine Dion and Justin Bieber songs over the in-store soundtrack. Now a human DJ will pick the music, and that's good news for shoppers, too. It's MORNING EDITION. Transcript provided by NPR, Copyright NPR.
