If the group leader is not available to select the assignment when the best appointment time starts, can the group member select into an assignment for the group?
No, a group member cannot select into an assignment for the group. If the group leader is not available to select the assignment when the best appointment time starts, the group leader should dissolve the group and allow a group member, who will be available, to reform the group so that s/he will be group leader and can select the group’s assignment at the earliest time possible.
