劳动合同法要求用人单位在一定条件下需要与员工订立无固定期限劳动合同。但是随着劳动合同法的推广,无固定期限劳动合同的实施并不乐观。文章主要分析无固定期限劳动合同对劳资关系产生的负面影响及其成因,并针对这些问题,提出有关建议,进一步推进无固定期限劳动合同发挥其在和谐劳资关系上应有的作用。 Labor Contract Law requires that the employer, under certain conditions, need to conclude a labor contract with a fixed term with an employee. However, with the promotion of the labor contract law, the implementation of a fixed-term labor contract is not optimistic. The article mainly analyzes the negative influence and its causes of labor contract without fixed term contract, and puts forward some suggestions to these problems, and further promotes the role that fixed term labor contract should exert in harmonious labor relations.
