A tenant union is a group formed by renters to advocate for their rights and improve living conditions. These organizations work together to address issues such as high rent, poor maintenance, and unfair eviction practices. By uniting, tenants can amplify their voices and negotiate better terms with landlords or property management companies. Tenant unions often organize meetings, share resources, and provide legal assistance to members. They may also engage in collective actions, such as protests or petitions, to raise awareness about housing issues. Overall, tenant unions aim to empower renters and promote fair housing practices within their communities.
