The general correspondence sub-series relates to all non-industrial relations issues. It includes correspondence with BOCSPA branch secretaries, with shopmen, and with individual members on issues relating to compensation claims and the Association's benefits. There is also wide-ranging correspondence connected with Spinners' Hall including tenants, hiring of halls and physical upkeep.
