What should you bear in mind when communicating with people from different cultural, religious, and ethnic groups?

What will be an ideal response?

When working with people from different cultural, religious, and ethnic groups, keep in mind
these guidelines:
a) Research the customs of the communities in which you do business.
b) Keep track of significant religious holidays that affect a company's employees and clients.
c) Do not make comments or jokes based on cultural or religious practices.
d) Do not imitate cultural language expressions or accents in an attempt to be friendly.
It is also critical that you know the business protocol in a country where you and your company
do business. It is important to be aware of regional differences and U.S. time zones.
