your interest in managing cultural diversities are really valuable. Such an issue is at the base of our work as community psychologists.
In the Community Tool Box, I suggest the whole Chapter 27. “Cultural Competence in a Multicultural World”, and, in particular, Section 2. “Building Relationships with People from Different Cultures”, the Main Section https://ctb.ku.edu/en/table-of-contents/culture/cultural-competence/building-relationships/main and the related Tools https://ctb.ku.edu/en/table-of-contents/culture/cultural-competence/building-relationships/tools
I find of interest also Section 4. “Strategies and Activities for Reducing Racial Prejudice and Racism”, where, as a tool, there is a PowerPoint presentation, very useful, which may be uploaded, on the page https://ctb.ku.edu/en/table-of-contents/culture/cultural-competence/reduce-prejudice-racism/powerpoint
I suggest you as well Section 7. “Building Culturally Competent Organizations”, and its Tools https://ctb.ku.edu/en/table-of-contents/culture/cultural-competence/culturally-competent-organizations/main
In each Main Section, Print Resources are indicated, so you can – if you want – analyze thoroughly the matter with further readings.
Many compliments for your awareness and sensitiveness and many wishes for your work!
