The relationship between an employee and an employer has been referred to as a “unequal relationship” since the dawn of time. Internally, this relationship always has potential risks of conflicts and disputes over rights and interests. Employees are almost always in a vulnerable position in almost all disputes, and they can scarcely use their limited strength to assert their legal rights. Many workers experience injustice and exploitation as a result of this imbalance, necessitating the involvement of a third party to protect the rights of difficult workers in particular and workers in general. After ratifying Convention No. 98 on Right to Organize and Collective Bargaining of the International Labor Organization (ILO) as well as signing new-generation free trade agreements (FTAs), Vietnam has codified many of its paramount commitments into the Labor Code 2019. In which, the articles that allow employees to establish their own organizations in the enterprise (not affiliated with trade union) appear for the first time. Because it is only regulated for the first time, there is no precedent in the labor law of our country and the legal provisions on the establishment and operation of this organization are still not specific, the author finds that researching the internal organization of employees in the enterprise is momentous on the basis of reference to ILO regulations. In this article, the author clarifies three assumptions: the appearance of internal employee organizations in an enterprise is unavoidable in the current situation, when Vietnam has just ratified the ILO’s convention and FTAs; the law on employee organization in enterprises, according to the Labor Code 2019, is still rudimentary, sketchy, and unclear; author’s suggestion for improving a company’s internal employee groups.
