According to the Migrant Workers' Labor Union, 150 dancers at Everland, the nation's largest amusement park located in Yongin, Gyeonggi Province, are subject to slave labor-type contracts...They work under individual contracts with Dong-il Entertainment, a manpower supply company that introduces dancers to Everland...Dong-il admitted unfair contents in the contract but said that they did not actually fine dancers for such causes...``Like foreign dancers at Everland, many migrant workers suffer from rampant slave-like contracts. They have no chance to get access to education or information regarding their labor rights or Korean labor law,'' said Han Seung-wook, an official from the Migrant Workers' Labor Union.
