A medical evaluation and substance testing are often required steps in the hiring process. These assessments help employers determine if a candidate is physically capable of performing the job’s essential functions and free from substances that could impair performance or create a safety risk. For example, a position involving heavy lifting might necessitate a physical examination to assess strength and endurance, while a transportation role might require screening for substances that could affect driving ability.
These procedures contribute to workplace safety, reduce potential liability, and promote a healthier work environment. They also ensure compliance with industry regulations and legal requirements. Historically, such evaluations emerged from concerns about occupational hazards and the need to protect both workers and the public. Over time, they have evolved to encompass a broader range of health and safety considerations.
