Jiang Chen, a salesperson, won important orders for the company and advanced entertainment expenses on business. However, the financial department refused to report the amount for a small amount just because it exceeded the standard, and his boss used perfunctory excuses to put pressure on him. He no longer tolerated it and insisted on safeguarding his rights according to the company's system, retaining evidence throughout the process and fighting back rationally. When faced with major projects, he first requires all reasonable expenses to be settled before taking over. In the end, due to long-term double standards between managers and finance and deliberate delays in the process, the cooperation was terminated, the company was damaged, and the relevant responsible persons were held accountable. Jiang Chen was promoted based on his professionalism and principles, promoted the improvement of the system, and guarded the bottom line of the workplace.
