By the end of the day, the company’s employees had organized their walkout using the newly formed @wayfairwalkout account on Twitter to garner support, and some people were already tweeting a #BoycottWayfair hashtag.

“We had gotten an anonymous tip from someone who worked there saying that the agency responsible for the detention centers placed a fairly large order and that there were people within the company that had a big problem with that, and we put that out there,” Matt Rivitz, who created Sleeping Giants, said in an interview. “This next wave of protest is not just consumer-oriented, but it’s also employee-oriented.”

Wayfair declined to comment on the walkout.

Social media has helped fuel a host of boycotts in the nearly three years since President Trump’s election. The online boycott campaign #GrabYourWallet pressured retailers like Nordstrom to stop carrying merchandise tied to the president’s daughter Ivanka Trump. Calls to #DeleteUber followed accusations that the company tried to profit from a protest against the president’s executive order barring refugees and immigrants from certain countries from entering the United States. L.L. Bean, New Balance, Kellogg’s and more have all found themselves at risk of politically motivated boycotts in recent years.

Lately, the pressure has also been coming from employees. At big technology companies like Google and Microsoft, workers have turned to petitions and walkouts to seek change, including around who they do business with. At Microsoft and Amazon, workers have objected to working with Immigration and Customs Enforcement.

At Wayfair, more than 500 employees signed a letter to the company’s leadership on Friday asking that the company cease doing business with the contractor, BCFS, and others involved in operating such facilities. The employees said that they were writing “from a place of concern and anger about the atrocities being committed at our Southern border,” and wanted to ensure that Wayfair had “no part in enabling, supporting, or profiting from this practice.”
