Throughout the 2010s, TS Entertainment became known for multiple lawsuits from its artists and staff involving workplace abuse, extortion, and failure to pay company employees.

[9] On September 26, 2019, it was announced that a former employee of TS Entertainment reported the label to the Ministry of Employment and Labor due to overdue payments, which was later forwarded to the prosecution.

[12] In March 2023, it was confirmed that a genuine MAMA trophy of B.A.P, a group formerly handled by TS Entertainment, was bought at a flea market in the Philippines.

The findings caused outrage among fans, who believed that TS Entertainment likely threw away B.A.P's first ever award after the company closed down, until it landed on a flea market in the Philippines.

[13][14] On November 27, 2014, the six members of B.A.P collectively filed a lawsuit against TS Entertainment in order to nullify their contracts, claiming unfair conditions and profit distribution.

[15] The following day, TS Entertainment issued a press release refuting the claims made, stating that "there have been neither such maltreatments to the artists nor unfair clauses in the contract".

[23] TS Entertainment released a statement on the same day, claiming that the two members suddenly "cut contact" with the company and group after the documents were sent.
