Diversity, Ethics, & Inclusion Education

You don't have to memorize every possible term that might offend someone. 

Instead, act professional.

Don't use idioms and slang.  Many terms that sound innocent to you were created as an insult. 

Be ready to apologize without making a big deal out of it.

Choose kindness.

Everyone should work in customer service early in their career. Some customers take out their frustrations with life on people they imagine "have to take it." Don't be that customer.
