I work for a mega corporation in the US and just got an email that they are making this change for 2019. I have no problems with them shifting holidays around, but the reasoning that MLK day is significantly more utilized than NYE is absurd. Every single person is gone for a 1-2 week period during the new year. I don't know a single person that takes off MLK day.
Oh the word "diverse workforce" also appeared in the email. There are only 2 black people that work in this entire building, and they're reception and security.
