The Federal Transportation Safety Board recently stated Provincial Ferry Operators have failed to effectively enforce its zero-tolerance substance abuse policy. As part of its investigation into several fatal ferry accidents, the board revealed a pattern of crew use of illegal drugs. Data in the HRIS showed significant costs associated with employee accidents, absenteeism, turnover, and tardiness due to workplace drug use. The company president of one of the ferries wants the Transportation Board to implement mandatory employee drug testing. The union opposes mandatory testing and states that the issue has never been brought to the joint safety committee. Management is wondering why no one is standing up for what is right and reporting coworkers who are impaired on the job. In this situation, what legally protected ground would mandatory employee drug testing violate?
