Unions have stopped trying to use Walmart’s day-after-Thanksgiving ‘Black Friday’ sales to launch public relations blitzes against the corporation, effectively conceding that the once-high profile efforts were making little headway toward organizing a union at the nation’s largest employer.

“We actually don’t have any events planned for Black Friday,” said Amy Ritter, spokeswoman for Making Change at Walmart, a nonprofit activist group funded and run by the United Food and Commercial Workers.
