The article states the minimum will apply to seasonal and part time employees - but AFAIK Amazon employs a lot of people on so called 1099 contracts - the nyt coverage seems to imply those will be unaffected:
"A global employment agency called Randstad, which had handled the recruitment process for Amazon, was also to arrange his shifts, manage him on the warehouse floor and pay him his near-minimum wage. After three months, if he had performed well, he could apply to be an Amazon employee, though there was no guarantee he would succeed."
Still, I seem to recall reading about extensive use of similar contracts at Amazon, more recently too.

Only example I've on hand is this ft article from 2013:
