Drug testing policies vary by employer. Determining which roles at a large retailer like Walmart are subject to pre-employment or ongoing screening requires understanding the rationale behind these policies. Generally, positions involving safety-sensitive tasks, operation of heavy machinery, or handling controlled substances are more likely to require drug testing.
The implementation of substance abuse screening programs aims to ensure workplace safety and reduce potential liability. Historically, companies in transportation, healthcare, and manufacturing have commonly utilized drug testing due to the high risk associated with impairment in those sectors. This has expanded over time, driven by regulatory requirements and a desire to maintain a productive and safe work environment.
