In June 2003, I paid 10 years according to social security. How many days of annual leave should I take this year?

According to China's "Labor Law", the length of annual leave is in calculate length. Generally speaking, employees who have worked for 10 years or more have annual leave of 10 days. So according to your description, you have paid 10 years according to social security before June 2023, and you should have 10 days of annual leave.

If the company gave you 10 days of annual leave in 23 years, then this 10 day should be your legal annual leave. The company should not deduct 10 days of annual leave. You can ask the company's human resources department to explain this situation and ask them to provide relevant policies and legal basis.

If the company insists on withholding your annual leave, you can complain to the local labor inspection department. They can investigate the company's behavior and protect your legitimate rights and interests.
