The petitions that were delivered to Apple's retail stores last week are coming back for a second round. The group says it's not satisfied with Apple's response.

The group that hand-delivered printed petitions to Apple's retail stores last week plans to come back for round two.

Last week, SumOfUs delivered boxes containing some 250,000 printed signatures from its petition asking Apple to require more "ethical" working conditions from its supply and manufacturing partners. In a statement issued this afternoon, SumOfUs said it plans to do it again.

Next Thursday the group is taking what it calls a "distributed" approach, delivering the same petition to Apple's stores anew. However this time, the group is plans to have "hundreds of its members" do the work at local Apple stores, not just a hand-picked few.
