A little background for clarity: I live in central Europe and talked with a friend about [blackface](https://en.wikipedia.org/wiki/Blackface). It is quite common in the Netherlands and Germany to darken your skin if you play the Biblical Magi. I told him that there is a de facto ban in the US to darken your skin. It is not a law, but you would get fired or not get a job if there are pictures of you wearing blackface. He did not believe me.

How likely are you to get fired / not get a job when you wore blackface in America? Can you speak of a de facto blackface ban in the USA? Or am I wrong and you can keep your job at Trader Joe's or Walmart? How is it for companies like Google or if you work for the goverment?
