I am not a deep household. At present, the company gives me second-class medical care, and I want to change it to first-class medical care at my own expense, but the company doesn't agree. What should I do? Do you know anything about secondary care? Whether the first gear is high or the third gear is high is estimated to be calculated by the company according to the comprehensive reality. If you change to the first file, I am afraid that other employees will not accept it, so I didn't agree to change the information for you. I suggest you go to the company and ask the person in charge of this area to find out or what they gave you. If the company can't solve it, you can consult the local social security bureau to see if they have other plans for you.
