What do members of the professional committee of the Bar Association usually do? Is there much social work?

The Bar Association belongs to a mass organization. Its managers are not paid in principle, because most of them are part-time. Suppose there is a professional member whose salary comes from the lawyer's membership fee. Its duty is to undertake daily routine meetings, such as coordination, such as investigations, such as scientific research topics and so on, according to the resolutions of the Bar Association. Part-time members are just empty posts, and there is not much social work.
