What should I do if the old cadres visit the unit because of the treatment?

Work together. The retired cadres of the unit visit the unit because of the treatment problem, because there are problems or requirements that need to be put forward to the unit, and they should cooperate with the work and solve the problems. Retirement means that according to the relevant provisions of the state, workers quit their jobs because of old age, work-related disability or illness, and they completely lose their ability to work (or partially lose their ability to work).
