Acknowledging Humanity

Companies often express the sentiment that culture is critical to success.  There is much talk about the war for talent.  We hear that people are the top priority.

If these statements are true, then I wonder why I still encounter, on a fairly frequent basis, the strange experience of passing colleagues in the hall, saying hello while passing, and getting absolutely no response in return.  How did these people “pass the test” for cultural fit?

I find it astounding that a person would disregard a coworker who says hello. Zero response.  No acknowledgement.  I think it’s rude, and shows a complete lace of emotional IQ.

Isn’t this a fair and reasonable expectation that people at least acknowledge humanity?  What do you think?
