Despite the millions of hours donated to charity each year by employees on behalf of their employers there has been relatively little research into the motives for such pro-social behavior. The current paper extends Peterson’s (2004, Journal of Business Ethics 49, 371) study by exploring a unique form of employee volunteerism identified as intra-organizational, or employer-sanctioned volunteerism, and uniting the heretofore distinct charity support and organizational citizenship behavior literatures. Results of a preliminary study revealed that employee participation in such intra-organizational (...) volunteer programs is motivated by charity, firm, and personal benefits. Managerial and research implications are presented. (shrink)
