I've recently been reading/watching some videos and writings by Robin Diangelo on systemic racism - here's a great starting point: https://www.youtube.com/watch?v=h7mzj0cVL0Q. She also wrote the book "White Fragility".
Thinking about that, I'm just wondering how different it would be if one of those people who mistook the employee for the CEO instead turned to the CEO and said "I'm sorry, please excuse me for the instance of racism I just perpetrated against you, I promise it won't happen again." I realize how outlandish that may sound writing that out, but I'd propose that the fact that it does sound outlandish is the main problem. Everyone in the US was raised in an environment that inculcated certain racial ideas, subconsciously or not. We can't address them if we're so embarrassed by their existence as to pretend they don't exist.
Even within her book she claims that no amount of training will solve the issue, it seems that "White Fragility" is just another way for White people to tamp down the anxiety of race relations in the United States, rather than take any meaningful action towards changing it.
If your goal is to truly understand the Black american experience, it's best to start with actual Black authors. The House That Race Built by Wahneema Lubiano is a great set of essays about race and class structures.
It's also problematic because the workplace inherently has an underlying adversarial quality that can provide a never-ending supply of "microaggressions" and various forms of otherings that effectively sow more division than actually get non-whites anywhere.
The author is particularly clever for writing a book for the target of anti-racism, because the market for "look who's racist" media is thoroughly saturated.
Since race is becoming a greater and greater issue, I imagine it will continue to become a get-rich-quick scheme for some adept to the English language, or the language of CorporateSpeak.
Its also the only place in adulthood where people willingly or unwillingly must work together with people different than them and not necessarily of their choosing to reach a common goal.
We're also free to find new jobs if we don't like them, but it sure is harder than those other choices.
