PKIU meaning in Community ?

The Printing and Kindred Industries Union (PKIU) was an Australian trade union which existed between 1966 and 1995. It represented production workers in the printing industry, including compositing, typesetting, letterpress printing, lithographic plate-making, electrotyping, stereotyping and bookbinding, and the manufacture of paper and cardboard products, such as paper bags, envelopes, cardboard boxes and cartons. Approximately half of all members were qualified tradespeople, with the remainder semi-skilled or unskilled workers.

As in many other printing trade unions, the union members in each workplace were known as the 'Chapel', and the senior union delegate as the 'Father of the Chapel', while other elected officials were referred to as 'brothers'.
