On Feb. 16, immigrants across the United States either didn’t go to work or to school as part of the protest “A Day Without Immigrants.”

Businesses closed and immigrants refused to spend money to support this protest. Some of the businesses that remained open pledged to share some of their earnings with nonprofits that aid Latino communities. The purpose was to show the Trump administration how much immigrants contribute to the country’s economy. According to The Washington Post, the strike spurred on a social media campaign. No national group organized this strike.

Many restaurant workers participated in this movement. According to CNN, Matt Carr, owner of the Little Red Fox in Washington, D.C., didn’t have a problem with his employees going on strike, even though those employees were a big part of his restaurant. However, before the workers went on strike, Carr says they made sure their job was done: “They not only gave me a heads-up about the strike but did double the work yesterday so we would be in good shape today.” Mr. Carr appreciated the hard work and dedication of these workers.

In contrast, a number of employees were nervous to ask their bosses to join the strike. According to CNN, a Mexican-American woman named Eunice Arcos wanted to join the strike but was nervous about what her bosses would say. She nervously sent a text asking if her bosses at Makeup On The Go Cosmetics were going to participate in “A Day Without Immigrants.” Her bosses granted her request by saying they would close to support the immigrant community.

Restaurants, from San Francisco to Washington, D.C., were the most visibly affected. Some well-known chefs closed their restaurants for the day. Also, according to The Atlantic, a handful of restaurants printed messages of solidarity on customer receipts such as “Immigrants make America great (they also cooked your food and served you today).”

Despite a great deal of success, there was also a downside to this day. According to CNN, there were a number of participants in the protest that were fired. Workers in Colorado, Tennessee, and Oklahoma, for example, lost their jobs for joining the protest. Twelve employees working at I Don’t Care Bar in Oklahoma were fired via text message reportedly for the company’s no-show policy. A neighboring restaurant offered jobs to those fired, saying that they were in demand of experienced restaurant workers.  The Atlantic says that the fallout of strikes will likely hit low-wage workers hardest because their workplaces don’t offer much protection and benefits, making the workers more vulnerable.

Many people across the United States participated in this peaceful protest. “A Day Without Immigrants” had one purpose: to stand with immigrants and to show the Trump administration how much immigrants contribute to the economy.
