BESSEMER, Ala. — Linda Burns was excited at first to land a job at the Amazon warehouse outside Birmingham, Alabama. The former nursing assistant had always enjoyed ordering from the company, Now, she would be working for them.

A cog in a fast-moving assembly line, her job involved picking up customers’ orders and sending them down the line to the packers. Now she is a staunch supporter of getting a union at the Bessemer facility. She said employees face relentless quotas and deserve more respect.

“They are treating us like robots rather than humans,” said Burns, 51, who said she is out of leave after developing tendonitis.

This week, Amazon workers and union advocates, including Vermont Sen. Bernie Sanders, made a last-minute push as voting comes to a close in the high-stakes union battle. If organizers are successful, it could lead to a chain reaction of other unionization pushes at Amazon facilities. If voted down, it would be another loss for organizers hoping to win a rare labor victory in the Deep South.

Amazon is fighting the union. The company argues the warehouse created thousands of jobs with an average pay of $15.30 per hour — more than twice the minimum wage in Alabama. Workers also get benefits including health care, vision and dental insurance without paying union dues, the company said.

Sanders spoke at a union rally in Birmingham on Friday, saying a labor victory against the tech and retail giant owned by the richest person in world — and in a historically anti-union state — would resonate across the country.
