Legal analysis: effective. If there is a typo, it belongs to the contract defect and can be corrected after both parties reach an agreement through consultation. As long as the contents of the labor contract are true and legal and do not violate the mandatory provisions of the law, it has legal effect.

Legal basis: Article 18 of the Labor Contract Law of People's Republic of China (PRC) is not clear about the standards of labor remuneration and working conditions, which causes controversy, and the employer and the employee can negotiate again; If negotiation fails, the provisions of the collective contract shall apply; If there is no collective contract or there is no agreed labor remuneration in the collective contract, equal pay for equal work shall be implemented; If there is no collective contract or the collective contract does not stipulate working conditions and other standards, it shall be implemented in accordance with relevant state regulations.
