In Oh My Ghost Clients episode 6 focused on something simple but real — respect and fairness. The story showed how even small jobs, like cleaning, deserve the same dignity as any other work.
Jung Kyung-ho’s character, Noh Moo-jin, took on a case that was personal. His own mother, Yang Eun-ja, works as a cleaner at a top university. At first, Moo-jin followed her out of concern. She had been acting strangely every weekend, and he wanted to know why. What he found wasn’t easy to watch.
In South Korea, labor disputes involving janitorial staff at universities are not fiction. In real life, universities like Yonsei and Korea University have faced similar union protests. This episode mirrors that reality.
Yang Eun-ja and the other cleaning ladies were being treated badly. Not for doing their jobs wrong, but for how they looked or spoke. They had to pass a “manners exam” — something that had nothing to do with cleaning. One of her coworkers, Kim Young-sook, even passed away from a heart attack while preparing for it.
This hit Moo-jin hard. He felt guilty for not noticing sooner and angry at the unfair system. That’s when he decided to step in. He joined the cleaning staff in protest. He stood in front of the school and asked for justice. His words were clear: the exam was cruel, and it needed to be stopped. He also asked for an apology for what happened to Kim Young-sook.
But things didn’t go smoothly. The police showed up, and the protest turned chaotic. Still, Moo-jin stayed strong. He argued with the officers, using the law to protect the protest. The janitors then formed a labor union to push for change together.
Students Push Back, Janitors Fight On in Oh My Ghost Clients Episode 6
The school didn’t like this at all. It threatened to cancel contracts if the strike continued. The janitors had clear demands: cancel the unfair exam, bring back a fired coworker, and give accident compensation to Kim Young-sook’s family.
In response, the school made a harsh move. It tried to turn students against the janitors. The strike had made the campus dirty. Bathrooms smelled, and trash piled up. Some students said they couldn’t study or focus during exams. They even threatened to report the janitors and sue them for causing trouble. But Moo-jin stood his ground. He asked the students to understand. He explained why the janitors were fighting.
“What’s the use of studying the law,” he asked, “if you don’t use it to protect the weak?”
Sadly, many students didn’t care. They saw themselves as the victims. This hurt the workers. Some wanted to give up. Moo-jin tried to stop them. He said quitting now would only make things worse. But the workers felt lost.

Then something unexpected happened. A few students offered their support. That gave everyone a bit of hope again. Moo-jin, along with Na Hee-joo and YouTuber Go Kyeon-woo, started looking for a new way to speak up. This time, they used the internet. Go Kyeon-woo did a live stream to tell the janitors’ story. Yang Eun-ja, Moo-jin’s mom, wore glasses with hidden cameras. She took the test again and recorded the questions. The video showed how unfair and strange the test was.
Victory Through Visibility and Advocacy
The live stream got attention fast. Students, graduates, and even news reporters watched. People started talking. Then the alumni group also showed support for the janitors.
That changed everything. The school finally responded. It agreed to stop the exam and improve the working conditions. Park Myeong-suk, who was unfairly fired, got her job back. The school promised to do better in the future.
And Moo-jin? He didn’t just fight for the workers — he gave them a voice. This wasn’t just a legal win for Moo-jin. For the first time, he saw the world through his mother’s eyes — not as a lawyer, but as a son. He made sure Kim Young-sook’s story didn’t get buried. This episode showed something important. Fair treatment at work isn’t too much to ask. Everyone deserves it — even those who clean the halls.
By highlighting these issues through a drama, Oh My Ghost Clients does more than entertain. It reminds viewers that respect at work should be a basic rule, not a bonus. And for Noh Moo-jin, helping the cleaning workers wasn’t just about the law. It was about doing what was right, even if the world didn’t make it easy.
