Bezos also noted that the net profit for Amazon in 2020 was $21.3 billion.
In relation to the recent unionization effort in Alabama, Bezos said he doesn't "take comfort in the outcome." The bid to establish a union at the Amazon warehouse was defeated by a 2-to-1 margin.
"I think we need to do a better job for our employees," he wrote. "While the voting results were lopsided and our direct relationship with employees is strong, it's clear to me that we need a better vision for how we create value for employees – a vision for their success."
Bezos will step down as Amazon CEO later this year, though he will remain in his executive chairman role on the Amazon board.
