I am a retired contract employee this year, working in a real estate in Chaoyang, Beijing 1 1 year, with a Beijing hukou. Is it reasonable for the unit not to retire?

It must be unreasonable. What is the reason why the unit does not retire? Are social security and medical care provided by the company or by yourself? If you pay it yourself, you will be unemployed if you retire, so it depends on whether the unit has paid insurance for you. When you pay the insurance, the enterprise will return the employees, and you can also complain to the labor inspection department.
