Continuous 12-hour shift operation at Harwood

A 12-hour shift roster was first tested at Harwood in 1991. This paper summarises developments of rosters at the work site, and reviews the advantages and disadvantages of a 12-hour shift roster versus an 8-hour shift roster. The topic is controversial and the decision on whether 12-hour shifts are appropriate for a site is likely to depend on the evaluation of intangible benefits.
