Hadden was a founding board member of the Participatory Budgeting Project, where she worked from 2010 to 2018 to bring participatory budgeting to cities in the Midwest and the South. She later served as the executive director of the non-profit Our City Our Voice. She also served on the boards of directors of the non-profit Voqal and of Black Youth Project 100. She has been an active member of Network 49, an independent political organization based in Rogers Park, and of United Working Families.On January 20, 2018, Hadden announced her campaign to run for alderman in the 49th ward, which covers most of Rogers Park and portions of West Ridge. After the submission and processing of ballot petitions, Hadden and incumbent Joe Moore were the only candidates to make it on the ballot for the February 2019 election. Hadden's campaign emphasized development without displacement, funding local public schools, and supporting a strong local economy as key issues in the race. She received several endorsements from progressive activist groups, labor unions, and local politicians such Chuy García and David Orr. Although both candidates self-identified as progressives, observers and media outlets generally characterized Hadden as challenging Moore from the left. Hadden won the election on February 26, 2019, with 63% of the vote. She won a majority of the vote in 32 out of 33 precincts in the ward. With her win, Hadden is the first queerwoman of color to be elected to Chicago City Council. After her election, Hadden said that in her first few months in office, she will pursue a full assessment of infrastructure and services in the ward and set up an advisory committee for community engagement. On April 10, 2019, Hadden joined six other newly-elected members of the City Council in protesting against the approval of tax increment financing for the Lincoln Yards and The 78real estate developments.

City-wide issues
City budget
Hadden was one of 11 aldermen who voted against Mayor Lori Lightfoot's proposed 2020 budget, alongside either other members of the Progressive Caucus. In a statement about her vote, Hadden stated, "I’m optimistic about the increased investments in housing, mental health care, homelessness prevention and concrete investments in the South and West sides of our city, but remain concerned that we haven’t exhausted all prospects of progressive revenue in order to take greater strides towards a budget that starts to repair decades of harm and inequity." Prior to the vote, Hadden spoke with constituents about the budget at multiple town hall meetings.
Public health
Hadden sponsored a "Senior Safety" ordinance, in collaboration with the Jane Addams Senior Caucus, that was passed in July 2020. The ordinance requires building managers in senior housing to conduct regular wellness checks on residents.
