#### Episode 128

On September 4, 2017, a major strike broke out with unions representing employees of the Korean Broadcasting System and Munhwa Broadcasting Company, complaining over unfair labour practices and government interference in news coverage by favouring Park Geun-hye, who at the time had been impeached for corruption. Both stations are effectively controlled by the government, with Korean Broadcasting the state broadcaster, and Munhwa 70% owned by the government. Both stations' heads are appointed by the government. The strike ended on November 15, 2017, after Munhwa president Kim Jang-kyom was fired, which was a demand of the union in this labour stoppage.
Upon the conclusion of the labour stoppage, Episode 128, which had been postponed nine weeks, was broadcast on November 19, 2017.
