The company has apparently schooled more than a million "supply chain employees" on rights and health and safety, while it has also began a specific environmental compliance program for some of its suppliers in China, having spotted several violations last year -- which it's now working on. Perhaps more interestingly, this notes the first time that Apple has revealed all 156 of its suppliers in full.

Update: MacRumors has published Tim Cook's team-wide email on the matter.
