Is it legal for employees to expel pregnant women without files?

Judge according to the specific situation. If an employee is not registered as pregnant, he may not be dismissed, which depends on the company's rules and regulations and legal provisions. According to the Labor Law of People's Republic of China (PRC), the employer shall sign a labor contract according to law and handle social insurance in accordance with the relevant provisions of the state. If the company violates the law, employees can complain to the labor inspection department or apply for labor arbitration. Therefore, whether employees can be dismissed needs to be judged according to specific circumstances, and professional lawyers can be consulted to safeguard their legitimate rights and interests.
