On July 30, 1996, the ACLU issued a statement charging that members of Explorer posts affiliated with public services had a significant advantage over non-members in finding employment with these services. Because the BSA prohibits its members from being openly homosexual or atheist, the ACLU believed these public services were discriminating against such people. On April 10, 1997, the ACLU filed a lawsuit against the city of Chicago for allowing these programs. Most of these problematic units were career-awareness posts affiliated with government agencies, especially law enforcement and fire service posts.
