This multi-method study examines Country of Origin (COO) as a measure at the individual level, in the work commitment literature. An International literature review uncovered that many of the existing empirical studies appear to share a common oversight in their approach to uncovering work commitment within multi-cultural contexts. These studies omit to include the COO variable and in doing so, create difficulties in drawing work commitment comparisons in multi-cultural contexts, such as Australia and the USA. This study provides evidence that the inclusion of COO as a measure in multi-method studies undertaken in multi-cultural contexts has the potential to yield a more accurate picture of work commitment.
