Racist code names for customers are bad. And, so is firing someone for complaining about it.

These are the key allegations underpinning ***Googles “underpinning”*** yes, underpinning a complaint filed in California against luxury retailer Versace.

Tell us more, Mayra Cuevas reporting here at CNN.com:

Can you fire employees for complaining about discriminatory treatment of customers?

No, dude.

Title VII of the Civil Rights Act of 1964 protects employees who oppose discrimination at work, as long as the employee was acting on a reasonable belief that something in the workplace may violate anti-discrimination laws. Title VII’s protections are broad and extend to complaints employees may make about how managers treat company customers. For example, this.

Of course, discriminatory code words for employees are hella-bad too.

So, train your workforce that code words are off limits — including code words about customers. And, anyone who complains about said customer code words should be taken as seriously as — and receive the same protections as — anyone one complains about “traditional” workplace discrimination.
