Do we need to hold an AGM/EGM to elect a new chairperson?
Our chairperson has resigned. Do we need to hold an AGM/EGM to elect a new one?
That depends on your constitution. Most would say that it's OK for the Parent Council/PTA committee to co-opt another member as 'acting' Chair. You could then wait until the next AGM or organise an EGM (Extraordinary General Meeting) at a convenient time.
