"Nestle signed an agreement in 2001 aimed at ending the use of child labour on cocoa farms"
BBC
News reported that Nestle was unable to keep to its promise of addressing child
labor . Likewise, the 2015 report of Fair Labor Association
expresses that child labor on Ivory Coast farms where Nestle sources its cocoa
is still evident . To make matters worse, the company made an
admission about the modern slavery and child labor in its supply chain in
Thailand where the company sources its seafood products. In
relation to all these, a group of consumers filed a class suit against Nestle
for failing to inform consumers that the chocolate products that the company
produces may contain cocoa from child labor.

As the children are duped into working in the cocoa
farms without pay apart from being brutally treated, Kantianism would likewise find
the practice unethical. The same holds true for consumers who are deceived into
believing that child labor is not used in producing the chocolate products of
Nestle that they consume .
