A group of foreign students working at a Hershey warehouse did not like the conditions, so they walked out of work on Wednesday.

The workers then picketed outside of the warehouse, located in Hershey, Pennsylvania, the Associated Press reported. They cited bad working conditions and an isolated atmosphere.

The walkout was organized by the National Guestworker Alliance.

The students paid $3,000-6,000 each to come to America this summer for what they thought would be a cultural exchange program, the NGA said on their Web site. Instead, they found themselves packing chocolates at the Hershey's plant in deeply exploitative conditions.

Hershey officials said the warehouse is run by a subcontractor who is expected to treat workers fairly, the AP reported.

The walkout has not affected company activity, the AP reported.
