John Hanks works at ProLogis. The company decides to institute a drug-testing policy. John is a good and longtime employee but enjoys smoking marijuana on the weekends. The drug testing will involve urine samples and, semiannually, a hair sample. It is nearly certain that the drug-testing protocol that Prologis proposes will find that Hans is a marijuana user. The company has made it clear that it will have a zero tolerance for any kind of nonprescribed controlled substances. John and several fellow employees wish to go to court to challenge the proposed testing as "an unreasonable search and seizure." Can he possibly succeed?
