Goodwill Group said Wednesday it will close its scandal-tainted temp staff unit Goodwill Inc. by the end of July because the health ministry is preparing to revoke its business license.

Goodwill Inc. said it will ask its clients to directly hire its temp staff assets or ask other temp staff firms to take them on by the end of next month.

Meanwhile, the company's 4,200 or so full-time employees will be asked to quit, it said, adding that the group is unable to transfer them internally because of financial problems.
