In short, yes. This should only happen in rare circumstances, and mostly councillors and clerk maintain cordial relations. However, councillors do not have the right to make demands of the clerk, or to take up their time unreasonably. The clerk is responsible to the council, and in order to be efficient, must have control of their time. Unfortunately, occasionally councillors fail to treat the clerk with proper respect. If the clerk feels threatened or if they feel that their work is being disrupted, then they are entitled to ask a councillor to leave or to exclude them.
