Big time companies that have not implemented Fair Trade:

Hershey's

Hershey's is one of the largest chocolate organizations in the world yet is doing a very poor job at implementing Fair Trade into their system. Apparently, they refuse to reveal who produces their cocoa. Though people know that their cocoa comes from Africa by the use of child slaves, they do not know their direct supplier. Looking at online articles about Hershey's and Fair Trade, I found that there was much complaint saying that Hershey's NEEDS to do something about who produces their cocoa. Article after article argued that Hershey's needs to change. Clearly, the issue wouldn't be such a hot topic had Hershey's not been one of the leading chocolate producers in the United States.

M&M Mars

As the largest chocolate and candy company in the world, M&M Mars has also failed to implement Fair Trade, just like Hershey's and Nestle. An article I read stated that the company was bombarded with thousands of letters and emails from children and adults and even confronted by several organizations purposing that they use Fair Trade. They refused. Not a single one of their products have Fair Trade labels on them; M&M Mars simply shuns the idea of Fair Trade.

Nestle

Nestle is also one of the largest chocolate organizations in the world. Like Hershey's, their chocolate supply comes from West Africa by child slaves who, as they are well aware of, are starved, unpaid, and abused under the rule of slave traffickers. Different from Hershey's, though, Nestle implemented Fair Trade into their line of coffee in England in 2005. Since then, however, not much process has been made. Nestle gains $65 billion every year; it's not like they can't afford to carry out Fair Trade.
