Is the recruitment of water supply companies a career series?

Generally, waterworks that have not been restructured are all prepared by public institutions, and there will be employees with both career and enterprise salaries. As far as your situation is concerned, the personnel bureau has no files, so it can be determined that it is compiled by the enterprise. If not, the retirement salary will of course be paid according to the enterprise establishment, which will be less than the career establishment salary, such as living salary, file salary and so on.
