Around 1877-ish, with "Wood's Rule".Why and when did the U.S. make such a policy?
What part of the Constitution do you imagine the Doctrine of At Will violates?It seems so unconstitutional
Some do, some don't. Who cares? We deal in US law here.Don't other countries make At-Will termination policies illegal?
As Betty notes, At Will goes both ways. If your employer sucks, you can leave without notice or legal repercussions.
