I graduated from junior college as a cadre, right? Now I have been admitted to the service establishment of public institutions through open recruitment. Am I a worker?

Basically, this involves the specific management of local institutions, and there may be regional differences. Generally speaking, workers can be employed as middle-level and lower-level cadres in their own units, but their status as workers remains unchanged and only posts are hired. For example, you can be hired as the director of the office, but you are still a worker.

If there is no formal establishment, only the employment establishment, then the cadre status will be retained.
