Heartland Workers Center is an organization founded in 2010 in Omaha, Nebraska as an advocacy group for Latino immigrant workers.  The Heartland Workers Center serves as an advocacy organization for left-of-center programs and policies in Nebraska, including participating in voter activation of left-leaning demographic groups and pushing for legal status for illegal immigrants.
Sergio Sosa, a left-of-center activist and current Executive Director of the Heartland Workers Center, launched the Center in 2009. The IRS granted tax-exempt status to the Center in 2010 as a 501(c)(3) organization. 
Though the Center brands itself as a workers’ rights organization, Sosa founded the Center after organizing an Omaha demonstration to protest Immigration and Customs Enforcement searches for illegal immigrants in 2006.  After leading the march, Sosa developed a permanent organization: the Heartland Workers Center.
Since its foundation, the Center became involved in a network of left-of-center organizations, including becoming a founding member of the Nebraska Civic Engagement Table (NCET). The NCET is an organization which mobilizes left-of-center voting blocs. 
The Heartland Workers Center focuses activism in three major areas: labor, voter mobilization, and expanded immigration.
The Center focuses on labor organizations and workers’ rights, running numerous programs from topics like sexual harassment in the workplace to leadership seminars. Alongside these programs, the Center offers counsel in certain employer-employee legal disputes. The Center is pro-unionization, putting together training seminars which educate workers on how to form and maintain a labor union. 
The Center has gained a reputation, and media attention, for its voter mobilization techniques, including knocking on doors of Latino voters in Nebraska to try to get them to vote in midterm elections.  Though a technically “nonpartisan” organization, part of the organization’s mission is “turning demographic change into political power,” referring to converting the increased Latino population in Nebraska into left-of-center policies. 
Aside from direct efforts to register new immigrant voters and convince registered voters to show up on election day, the Center spent over $150,000 on lobbying in 2017 alone. 
Immigration is at the core of the Heartland Workers Center’s activism, given that the organization is expressly designed to serve Latino immigrant workers and refers to itself as a “Nebraska immigrant advocacy” organization. 
The organization has taken strong stances against President Donald Trump’s immigration policies.  Even in its push to register new voters, the Heartland Workers Center has taken an explicitly anti-Trump stance, with the chief of strategy reporting that she convinced one immigrant Latino citizen to register “just to be able to vote against Trump.” 
Several projects organized by the Heartland Workers Center are targeted at left-of-center immigration reform with strong biases against conservative policies. One of these programs, the Young Nebraskans in Action program, “educates others about Dreamers who found protection under…Obama’s federal Deferred Action for Childhood Arrivals program now under threat by President Donald Trump’s administration.”  Heartland Workers Center officials have also made comments against the Trump administration directly, saying that Trump policies have incited mass panic among illegal immigrants for the first time in a decade. 
The Heartland Workers Center’s efforts have been acknowledged by Democratic Nebraska legislators Tony Vargas and Megan Hunt, who called on citizens to support the Heartland Worker’s Center in pushing for left-of-center immigration reform.  Though claiming not to be aligned with any particular candidates or political parties, the group has refused any opportunities to engage with right-of-center thinkers on immigration. Sosa, the Executive Director of the Heartland Workers Center, was supposed to participate in a panel at Creighton University, alongside other left-of-center and right-of-center leaders. Sosa and the other left-of-center panelist dropped out of the panel three days before the event, saying they would be “happy to host a conversation by community groups on incursion” instead of participating in the event.
