How many Code of Conducts have been added to repository since people have been asking for them?
The collective bargaining I was suggesting was to talk with your own companies which have a business relationship to Kellog.
Work in a hotel that has minicereal boxes? Get with purchasing to stock a different brand. Work in a grocery? Ask the owners to stock a different brand on a public forum.
See Kellogg flakes at a friend's or family's house? Ask them politely not to support union busting.
Daily call one local business until they agree not to stock Kelloggs.
