In the roughly three weeks since Donald Trump took office, he has swiftly delivered on his proto-fascist campaign pledges, unleashing a flurry of executive orders and ushering in a cabinet populated with white supremacists. Yet each move has been met with popular resistance on a stunning scale. Trump’s inauguration was greeted with massive protests in Washington, D.C., and across the country. The following day saw millions around the world take to the streets under the banner of the Women’s March. And when Trump implemented a ban on both refugees and holders of visas and green cards from seven Muslim-majority countries, thousands flocked to airports across the country to demand the immediate release of people detained.

In cities, towns and rural areas, communities are training to defend their neighbors from immigration raids, a form of preparation that proved necessary this week in Arizona, when Guadalupe García de Rayos was torn from her family and deported to Mexico. Public workers are resisting the Trump administration’s gag orders, with National Park Service employees among others declaring they will “not be silenced.” There are numerous calls for boycotts, work stoppages and large-scale campaigns of non-cooperation amid the groundswell, with some nodding toward South Africa’s anti-apartheid struggle with the cry of “become ungovernable.”

AlterNet spoke with some of the organizers behind the multiple calls for mass strikes to learn more about how this tactic factors into the growing resistance movement.

May 1: A Day Without Immigrants

Movimiento Cosecha, or Harvest Movement, plans to go on the offensive under the Trump administration by organizing a week-long migrant strike of five to eight million workers. Led by undocumented people and immigrants, including veteran Dreamers, Cosecha will build toward this larger goal with a one-day strike on May 1, also known as May Day or International Workers’ Day.

“On May Day, Movimiento Cosecha will be having its first of many boycotts and strikes under the theme of Un Dia Sin Inmigrantes [a day without immigrants], which resonates with immigrant communities across the country,” Carlos Rojas Rodriguez, an organizer with Cosecha, told AlterNet. “We are encouraging allies and the American public to stand with immigrants across the country by not going to work, not buying any products and not going to school. In order for strikes and boycotts to be effective, they have to also be disruptive and visible to the public.”
