Religion and spirituality are increasingly being recognized as significant dimensions of diversity in the workplace. There are two models for religious Employee Resource Groups (ERGs): religion-specific ERGs and interfaith ERGs where all religions are celebrated in one group. The Interfaith ERG is emerging as the preferred model for large companies. It may be more difficult for large organizations to manage the business goals of multiple faith-specific ERGs. Furthermore, given the diversity of religious beliefs and practices across the globe, companies could be challenged by the number of employees wishing to form separately operating religion-specific ERGs. Interfaith ERGs are an inclusive way for all employees to connect over their beliefs and learn about others, while reducing the possible tension that arises when religion enters the workplace.
