Legal analysis: to sign, the employee handbook is generally a collection of company systems. The employee signature in the employee handbook is beneficial to both employees and employers, which not only avoids the unreasonable punishment and dismissal of employees by employers, but also provides a basis for managing employees. So no signature is invalid.

Legal basis: Article 25 of People's Republic of China (PRC) Labor Law can terminate the labor contract at any time, including "serious violation of labor discipline or rules and regulations of the employing unit". However, if the employer has no regulations or unclear regulations, it will be passive because there is no basis or unclear basis. Making a legal Employee Handbook is the right given to enterprises by law and the necessity of enterprise management.
