Briquette sales staff at Yallourn, JP Campbell, photographer, c1930–50, JP Campbell Collection of glass negatives documenting industrial enterprise at Yallourn, State Library Victoria Pictures Collection.

Yallourn workers and residents colloquially referred to those employed in professional and administrative roles as 'staff', and skilled tradesmen and labourers as 'wages'. This photograph by JP Campbell shows 'staff' in the briquette sales office. Briquettes were made from brown coal at Yallourn and were used both for domestic heating and to power industrial furnaces. Household briquettes were stamped with the letter ‘H’ while industrial briquettes were marked with an ‘I’.
