In this paper we present findings of how employees from a single organization understand corporate sustainability. Responses from 255 survey participants indicate (1) that differences exist in how employees understand corporate sustainability and (2) that these differences can be partially explained by the presence of organizational subcultures and by differences in employee awareness of the organization's sustainability practices. In particular, findings reveal that employees from a subculture with a stronger emphasis on hierarchical and bureaucratic values emphasize an economic understanding of corporate sustainability. Implications for research and practice are discussed. Copyright 頲007 John Wiley & Sons, Ltd and ERP Environment.
