Workers struck at Walmart in Pico Rivera, Calif., on Nov. 20, demanding an end to retaliation against workers who speak out. On Nov. 23, the day after Thanksgiving, demonstrations and some strikes occurred at about 1,000 Walmart stores in 100 cities for better wages and working conditions. On Dec. 14 workers in the U.S. and nine other countries rallied at Walmart stores and subsidiaries, denouncing retaliation against workers trying to organize. This followed a one-day strike at a Walmart supply warehouse in Mira Loma, Calif., over unsafe and unsanitary conditions, and a three-week strike at a Walmart supply warehouse in Elwood, Ill., over sexual harassment, dangerous working conditions, unpaid wages and retaliation against organizers. The Elwood workers won full back pay and a promise to end workplace retaliation.
