"40-Year-Old Workplace, No Room for Tears" focuses on the survival dilemma of four middle-aged men, Liu Zhijun, Yu Hong, Sun Jie, and Wang Pengtao. Construction engineer Liu Zhijun adheres to professional ethics and exposes the shady secrets of the project but faces unemployment. His wife's serious illness makes him even worse. Internet operations director Yu Hong is replaced by a younger subordinate. As his career declines, family conflicts become increasingly intensified. Sales manager Sun Jie suffers from customer losses, marriage breakdown, and has to pay for the rehabilitation of his autistic daughter. Doctor Wang Pengtao is caught in the vortex of public opinion due to a medical accident, and his son's mental health problems also make him mentally and physically exhausted.
They struggle between the workplace and their families, endure the anxiety of being abandoned by the times, and swallow the bitterness of life. From being laid off and demoted to being slandered and betrayed, from marital crises to serious illness of relatives, they have been struck down by fate time and time again. But in the darkest moment, the four chose to support each other and find a turning point in the desperate situation. Some people bravely report the chaos in the industry, some people relearn to adapt to the times, and some people transform and start businesses to open up new paths. The story truly shows the hardship and tenacity of middle-aged men, and conveys the power of never giving up and rebirth in difficult situations.
