You have formed a de facto labor relationship with the enterprise. According to Article 93 of the Labor Contract Law and judicial interpretation, the employer cannot refuse to take responsibility on the grounds that it has no business license.

You can complain to the labor inspection agency about the employer. You can apply to the labor dispute arbitration commission for arbitration.

Judicial Interpretation of the Labor Contract Law Article 4 In the event of a dispute between a laborer and an employing unit that does not have legal business qualifications, the employing unit and its investors shall be regarded as joint parties. If an employing unit that does not have the legal business qualification borrows the business license of others, it shall also take the party that lent the business license as the party.

In the event of a labor dispute between a laborer and an employer to which another unit belongs, the employer and the subordinate unit shall be the common parties. (Article 93 of the Labor Contract Law; Article 4 of the implementing regulations)

Article 93 of the Labor Contract Law shall investigate the legal responsibility for the illegal and criminal acts of the employing units that do not have legal business qualifications; If the laborer has already paid labor, the unit or its investors shall pay labor remuneration, economic compensation and compensation to the laborer in accordance with the relevant provisions of this Law; If it causes damage to workers, it shall be liable for compensation.
