Seyfarth Synopsis: On May 29, 2020, the Rhode Island Supreme Court affirmed dismissal of an employee’s lawsuit against his former employer after it terminated him for refusing to submit to a reasonable suspicion drug test, even though his “bizarre” behavior could have been attributed to other causes. As employers are becoming increasingly concerned about marijuana use in states with recreational or medical marijuana laws, the decision serves as a reminder to employers to develop a process for making and defending a reasonable suspicion determination (including manager and supervisor training and objective and clear documentation).
