Cereal production at Kellogg’s U.S. cereal factories, where 1400 workers are on strike, has plummeted. Kellogg’s is having to rely on products made in Mexico and Canada. The company now admits there is a “temporary shortage” of its brands. The strike is working.

Kellogg’s workers walked on out October 5 to an end to 80-hour workweeks with 16-hour forced overtime shifts, and to eliminate the company’s unjust tier system that gives new hires far less pay and benefits than more senior employees.
