In July 2013, accountant Liu joined Zhejiang Pengzhou Construction Company in an administrative role. Due to management oversight, Pengzhou failed to sign a labor contract or provide social insurance for Liu, who not only concealed this but also deliberately covered it up while quietly collecting evidence unfavorable to the company. During this period, Liu fell seriously ill and needed medical treatment, and Pengzhou provided necessary financial support to help him through the crisis. By February 2014, both parties terminated the labor relationship and reached an agreement on compensation and handover. However, a few days later, Liu applied for labor arbitration at the district labor arbitration committee, demanding various payments from Pengzhou, including double wages for the unsigned contract, overtime pay for weekends and holidays, unpaid wages, economic compensation for illegal termination, medical compensation, one-time unemployment insurance, economic compensation for wage arrears, and legal fees, among others. Pengzhou decided to entrust the arbitration case to the lawyer team of Wang Tengfeng from Guangdong Zhiming Law Firm. Team lawyer Zhang Qingping and trainee lawyer Ye Huijuan were responsible for handling the case.

After collecting all materials regarding Liu's position, Attorney Zhang Qingping concluded that Pengzhou Company's internal management was chaotic, with a large number of employee onboarding and resignation documents incomplete. However, Attorney Zhang Qingping believed that Liu's claims still contained many unreasonable and illegal aspects that could be refuted. First, Liu miscalculated the amounts for "double wages for not signing a labor contract," "economic compensation for illegal termination of the labor contract," and "attorney fees," exceeding the actual payable amount by more than three times. Second, regarding the claims for "overtime pay on public holidays and national holidays" and "insufficient wages," based on the collected "Management Attendance Sheet" and "Liu's January-February 2014 Salary Sheet and Others," it could be calculated that the company had fully paid Liu's overtime and wages. Third, the claim for "one-time unemployment insurance" is not a matter for labor dispute resolution, and the claim for "economic compensation for overdue wages" has no legal basis whatsoever; both are not recognized. Finally, regarding the claim for "medical compensation," although Liu provided hospital fee receipts, since it was impossible to distinguish which expenses fell under the "basic medical insurance treatment standards" for reimbursement, the company was not required to bear the above costs.

In the subsequent arbitration hearing, Attorney Zhang Qingping successfully persuaded the arbitration tribunal based on the above research and analysis results. Ultimately, the arbitration tribunal issued a ruling, significantly reducing Pengzhou Company's liability from the total of 145,000 yuan claimed by Liu to only 43,000 yuan, thereby protecting Pengzhou Company's legitimate interests to the greatest extent possible and preventing the malicious intentions of unscrupulous individuals from being fully realized.
