On the one hand, yeah, you should respect people who are different from you. On the other hand, this is really so obvious that I doubt elevating it to a “core value” makes much of a difference. Are there marginal people who wouldn’t respect diversity unless it was a core value?

Then again I don’t even know what it means for something to be a core value. What is the practical upshot of “collaboration” being a core value of a company? Were people not collaborating before?
