AMHERST -- On Friday, a day after many businesses closed to show the impact of immigrants in the country, activists are calling for a national strike, including one at the University of Massachusetts.

Strike4Democracy is organizing more than 100 strike actions across the United States including three in Boston, according to its Facebook page.

The purpose of the strikes, the Facebook post states, is "to stand up for America's democratic principles. As the nation suffers through ICE raids, travel bans, Trump's mobilization on the border wall, as well as attacks on the rights of workers, women, people of color, the LGBTQ+ community, and our environment, February 17th provides a beacon to those who are searching for a way to protect and defend our shared humanity."

The UMass Amherst Sanctuary Campus Movement at UMass is calling for a related strike to hold a teach-in addressing immigration issues.

According to its Facebook post announcing the event, the group wants students to "educate ourselves on resisting the continued and intensified oppression immigrants face in the United States. We will learn how to join and strengthen existing direct action networks, how to establish and maintain one here on campus, and how to make our community a real sanctuary."

The group is asking that students refrain from "financially supporting UMass, with the exception of the People's Market and Earth Foods."

The UMass Amherst Sanctuary Campus Movement has been calling on the university to become a sanctuary campus since November following the election of Donald Trump as president.

A federal appeals court has upheld a freeze on Trump's controversial travel ban on nationals from seven predominantly Muslim nations. The Trump administration is looking at other options.

On Jan. 27, Trump signed an executive order barring nationals from Iran, Iraq, Libya, Somalia, Sudan, Syria and Yemen from entering the U.S. for 90 days. The order also banned refugees from entering the country for 120 days, and halted the entry of Syrian refugees indefinitely.

According to the Sanctuary Campus Movement Facebook post, more than 100 people are going and another 200 are interested in the strike.

Organizer Anna-Claire Simpson said those who teach and other labor union members are not allowed to strike, which might limit the numbers.

And she said the weather is limiting an outdoor rally or march. "It's bringing people together for education," she said of the day's intent.

"We're still pressuring our administration -- the whole UMass system (to create a sanctuary campus)," she said.

"(The Trump policies) have a huge impact on our school," she said. "There's a lot of fear." Students who have green cards are afraid to leave the state even though they have legal documentation.

She praised Chancellor Kumble Subbaswamy for his response Feb. 2 to the campus and the creation of the Angel Fund to help immigrants with financial needs.

"I remain committed to the welfare and success of all members of our community, whether they be student, faculty or staff, and pledge to do everything within our legal and moral authority to protect them, no matter their national origin, race, religion, socioeconomic status, sexual identity, disability or immigration status," Subbaswamy wrote.

But Simpson said the Sanctuary Campus Movement wants to "put pressure on for a more tangible commitment."

Some on campus don't agree with the movement. Daily Collegian columnist Bradley Polumbo wrote, "If UMass was to take steps to defy federal law in an effort to protect such a small group of students, the potential of losing some or all federal funding could be absolutely disastrous for all members of the UMass community, regardless of their legal status."

Trump has threatened to pull funding in a variety of arenas including the University of California at Berkeley following violent protests there Feb. 1.

Simpson said the threat is making people afraid, but she wrote: "I wish it wasn't necessary to articulate this, but I know the school is stoking a lot of fear right now.

"Please don't fall the for the line that Sanctuary campuses (cities, etc.) are dangerous because they might invite federal retaliation of some sort. The real danger is racism, xenophobia, and the oppressive policies and laws which make movements (like Sanctuary) necessary."

Students will gather at 10 a.m. in the Student Union.
