Amazon 'used neo-Nazi guards to keep immigrant workforce under control'

Being from Germany, I had not heard of this before. Will be quite interesting to see how this plays out.

Most interesting part of the article IMHO was, that the spokesperson from amazon, did not deny the pay-cuts, but only said, the will investigate the security-firm, as the do not tolerate discrimination. But aren't (if true) these kinds of pay-cuts exactly that - discrimination?
