No, I’m not surprised that

Amazon workers voted against having a union.
They know Bezos would fire anyone who would not accept his shameless Dickensian 19th century job conditions.
They (and their families) want to survive and get ahead.
They know what side their bread is buttered on.
Forced slave labor (with no bathroom breaks) in America.
Pity, as I do, those workers who are that exploited (along with all the health care workers, overworked, underpaid, devalued, and taken-for-granted on both sides of the border).
