International player union FIFPRO is ready to issue a formal complaint against South Korea’s soccer association and top-flight domestic league for agreeing on an “inexplicable” new standard contract without the consent of professional players.

FIFPRO issued a statement saying the agreement, which means that Korean players in the K-League would be obliged to move teams if another club offers better terms, is a violation of player rights.

“I’ve never heard of it elsewhere — a player not being able to decide where his future is — and I’ve been in football for a long time,” Jason Davidson, an Australian who plays for K-League club Ulsan Horangi, told the Associated Press on Wednesday. “The K-League should be aligned with everywhere around the world. It is a basic rule in any workplace that you can decide where you work and where you live.”

FIFPRO, which consists of 65 national players’ associations, said the KFA and the K-League did not engage with the Korean Pro-Footballers Association on the amendment of contract conditions, which was at odds with the regulations of soccer’s world governing body on the status and transfer of players.
