Although defined in numerous and sometimes inconsistent ways in the literature, diversity climate can be described as employees’ shared perceptions of the extent to which their organization values diversity as reflected in the policies, practices, and procedures that the organization rewards, supports, and expects. Diversity climate studied at the individual level (individual perceptions of the impact of the work environment on the individual’s own well-being) is referred to as psychological climate. When it is conceived of and studied at the group or organization level (employees’ shared perceptions of their work environment aggregated to the unit level), it is referred to as group- or organizational-level climate. Two consistent criticisms raised in recent reviews continue to plague diversity climate research. These can most simply be stated as a lack of clarity about what diversity climate is and is not, and inconsistency in how diversity climate is measured and aligns (or does not) with how it has been conceptualized. Despite these criticisms, there is evidence that diversity climate can positively impact individuals’ (especially minority group members’) work-related attitudes (e.g., organizational commitment, satisfaction) and unit-level outcomes (e.g., performance). As a result, diversity climate is both practically relevant to organizations and conceptually meaningful to researchers.
