In this dispute Aarons played not only a significant part in organising among the CPA membership, but also in developing and propounding the ideological basis for the CPA's new policies and helping to write key documents for the Congress.
In 1974 Aarons returned to full-time work for the CPA as Editor (later Coordinator) of the CPA's weekly paper, Tribune, following the tragic early death of the then editor, Alec Robertson.
