Immigrants working low-wage jobs, especially undocumented immigrants, are particularly vulnerable to workplace violations. Empowered by the Immigration Reform and Control Act, employers retaliate against immigrant workers who complain about workplace conditions, discouraging workers from reporting violations. As a result, immigrant workers often underreport workplace violations due to a lack of confidence in legal remedies. Because of the Supreme Court's decision in Hoffman Plastics, undocumented workers are generally not entitled to back-pay, and employers can demand discovery of immigration status. Moreover, the civil and criminal legal systems systematically discredit the stories of immigrants facing workplace abuse. This Note argues that unions serve as one mechanism for protecting immigrant workplace rights. Immigrant workers can be empowered to assert their rights through organizations that investigate and sue on their behalf. As illustrated by the Aramark decision, unions can step into this role while providing a shield of anonymity against retaliation. Furthermore, existing labor laws like California's Assembly Bill 450, which requires notifying unions before workplace raids, can protect immigrant workers. Unions can also structure collective bargaining provisions to immunize workers from adverse action and shape employer practices by restricting E-Verify use, since unilateral E-Verify implementation violates Section 8(a)(5) of the National Labor Relations Act. Finally, this Note argues that Section 7 of the Act can protect immigrant organizing when immigrant rights are linked to job security and other working conditions under the Eastex "mutual aid" framework. In addition to protecting existing rights, this Note suggests that unions can play an expanded role in broadening immigrant workplace rights. Union education can serve two goals:(1) informing immigrant workers on how to exercise their rights; and (2) educating non-immigrants to prevent immigrant isolation and build collective power. Unions can also provide "diversified" legal representation with competency in immigration issues, which strengthens the efficacy of legal advice for immigrants while facilitating immigrant-friendly bargaining and arbitration. While immigrants have historically faced barriers to union participation, unions can center immigrant voices by promoting goals and policy that stress unity as well as implementing diversity within a union's bargaining structure. As exemplified by SEIU members' Justice for Janitors campaign against sexual harassment in the janitorial industry, immigrant-led outreach and advocacy has tremendous potential to revolutionize workplace rights through collective power and legislation not only for unionized immigrants but for entire low-wage industries.
