Article 91 of the Labor Contract Law stipulates that if an employer hires a worker whose labor contract with another employer has not been rescinded or terminated, and causes losses to other employers, it shall bear joint and several liability for compensation. It can be seen that when the HR company recruits workers, if it recruits workers whose labor contracts have not been terminated, the HR company needs to bear the liability for compensation when it causes losses to the relative employers. On November 15, 1995, Instrument Company A signed a non fixed term labor contract with Mr. Li and has been paying social insurance for Mr. Li. On March 28, 2005, Mr. Li signed the "Technical Personnel and Employment Agreement" with Zhejiang B Company without terminating the labor contract with A Instrument Company, with the term from March 28, 2005 to March 27, 2011. During this period, Instrument Company A informed Mr. Li to report back to the company, but Mr. Li did not respond. A Instrument Company applied for labor arbitration in December 2008, and provided evidence that Li earned 650000 yuan for A Instrument Company from July 2002 to December 2003. Based on this, it was calculated that Li's employment in Zhejiang B Company from March 2005 to December 2008 led to a decrease of 1.3 million yuan in the profits of A Instrument Company. The arbitration award awarded Li a compensation of 1.3 million yuan for the economic losses of A Instrument Company, Zhejiang B Company is jointly and severally liable for 700, that is, 910000 yuan, and has ruled that Mr. Li should bear part of the social insurance money returned to A Instrument Company. Mr. Li and Zhejiang B Company filed a lawsuit against him to the court, and then went through the second instance. The final judgment was basically the same as the arbitration result. It can be seen from the above cases that when an enterprise recruits employees, if the employee does not terminate the labor relationship with the previous unit, the enterprise will be jointly and severally liable for the losses of the original unit. Article 6 of the Compensation Measures for Violating the Labor Contract Provisions of the Labor Law (No. 1995223 issued by the former Ministry of Labor): "If an employer hires a worker whose labor contract has not been terminated and causes economic losses to the original employer, in addition to the worker's direct liability for compensation, the employer shall bear joint and several liability for compensation. The share of joint and several compensation shall not be less than 70% of the total economic losses caused to the original employer. Compensate the original employer for the following losses: (1) Direct economic losses caused to production, operation and work (2) Economic losses caused to the original employer due to obtaining trade secrets. Compensation for the losses specified in sub paragraph (2) of this Article shall be subject to the provisions of Article 20 of the Anti Unfair Competition Law. " Jin Haoyang, the company's contract lawyer, reminded that when recruiting employees, except for new workers, enterprises must check their written certificates of termination and dissolution of labor contracts before signing labor contracts and establishing labor relations with them. In particular, some knowledge-based, technical and marketing executives should be strictly examined, and they can sign labor contracts only after they accurately confirm that they do not have the obligation to keep business secrets and non competition with the original unit.
