In practically every big company. It isn't as much power or voice as much as litmus tests that serve to veto good stewardship.

This doesnt mean big company Directors and Executive Directors are not deserving of their promotions, it just means that they usually have an added hoop to jump thru -- increasing headcount.

I've been in senior ranks of big companies, and spoke to plenty of counterparts at other companies, and it is almost always the story.

Any company that allows HR to veto any promotions is royally screwed.
