Amazon is taking an unusual step to push back against critics of the company's labor policies: It's enlisted a group of Amazon warehouse workers to speak out over Twitter.

For over the past week, the "Amazon FC Ambassadors" have been on Twitter, defending the company against accusations that the e-commerce giant has been treating its workers poorly. They've been tweeting back to concerns and reports that they allegedly receive low wages and must pee in bottles because they have no time for bathroom breaks.

"Speaking on my own behalf, I can tell you that I've never seen anyone pee in a trash can or bucket before," tweeted one ambassador, who works in an Amazon facility in Texas. "We have all the restrooms and water stations a warehouse worker could ask for!"

The Amazon FC Ambassadors were initially called out by a Twitter user, who immediately suspected they were an army of automated bots. However, Amazon has been telling journalists that the ambassadors are all real employees that work at the company's fulfillment centers, where deliveries are prepared.

"The most important thing is that they've (the ambassadors) been here long enough to honestly share the facts based on personal experience," Amazon told PCMag. "It's important that we do a good job of educating people about the actual environment inside our fulfillment centers."

Recently, Amazon's labor practices have been facing scrutiny across the world. Last month, trade unions in Spain and Germany held strikes against the company, claiming that the e-commerce provider was getting rich off the health of its warehouse workers. An undercover author has also published a book, documenting the allegedly "grueling" conditions employees face at company delivery centers in the UK.

However, the Amazon FC ambassadors have been offering a different story. "I am treated well — my safety/well being are a priority for my managers," tweeted an ambassador named Phil, who works in a Washington state warehouse. "The building is clean and I have great benefits," he added.

"Uh… no… We do get bathroom breaks and can use the restroom any time we need without fear of a penalty for doing so," tweeted another ambassador named Caleb.

They've also been tweeting that, yes, they are real people, and not bots running automated scripts. Becoming an ambassador was also apparently optional. But whether their tweets will change anyone's opinion about Amazon is another matter. Other Twitter users are starting to rename their screen names as "FC Ambassadors" in an apparent attempt to mock Amazons PR effort.

However, Amazon is encouraging any concerned members of the public to schedule a tour at a company fulfillment center to view the conditions for themselves.
