Vote counting began on Tuesday to determine if workers in Bessemer, Alabama, will form the first-ever labor union at an Amazon warehouse in the U.S.
"It could be a real shift if we started to see organizing at Amazon.".
Colvin said a union formation in Alabama could set a "precedent" and inspire other Amazon workers across the country to follow suit.
"Amazon has a lot of facilities around the country and a lot of employees," he added.
"If this is the start of a broader movement towards unionization at Amazon, that would be a big deal to the economy.".
The Alabama workers' unionizing efforts have drawn support from lawmakers on both sides of the aisle.
Last week, Sen. Bernie Sanders, I-Vt., visited Alabama to meet with some of the workers involved in the unionizing efforts. »
