The present study tested an extended version of Voydanoff's "differential salience vs. comparable salience model" in a sample of German service workers. Our findings partially support the model in a different national/cultural context but also yielded some divergent findings with respect to within-domain resources and boundary-spanning demands. In line with the theoretical framework, work-to-home interference (WHI) mainly occurred because of high work demands and not because of a lack of work resources. Boundary-spanning resources yielded comparable potential to reduce WHI and enhance work-to-home enrichment (WHE). WHE was expected to more likely occur due to the activation of work resources rather than the absence of work demands. However, control over one's work did not have a significant impact on WHE. In addition and contrary to the theoretical model, boundary-spanning demands were found to be differentially rather than comparably salient to the work-family interface.
