kpop1-9, Exercise 1: The 2017 trainee rules

Model answer:

On 7 March 2017 the Korea Fair Trade Commission passed regulations to protect trainee idols from unfair terms and working conditions; the Ministry of Culture applied them to all existing agencies through 2018.
Before them, trainees at eight agencies were not permitted to seek contracts at any other agency while training, and agencies could terminate a trainee contract at any time for any reason.
The industry's concern: that a trainee might train undercover at another agency, and that each trainee (three years' training on average) is a very large investment for the agency.
A testimony reported without a company response (such as Hanni's in September 2024) is one party's account as reported; without the other side or a finding, it should be reported with its owner and not treated as established fact.
