Perhaps Amazon needs a little anti-trust love.
Unions are labor mafias that extort money from companies or government. They do whatever they can for workers at the expense of people that rely on those workers.
Furthermore they are just political machines for uber liberals and other leftwingers. I've seen unions endorse candidates that actively are working against their workers interests just for politcal endorsements.
Jeez, will unionizing really take that much out of Amazon’s bottom line that they need to stoop to this level?
