Step-by-step explanation:
A staffing firm may choose to have pre-employment drug testing for specific roles for several reasons:
- To ensure a safe and drug-free work environment.
- To minimize the risk of workplace accidents or incidents caused by employees under the influence of drugs.
- To comply with legal requirements or industry regulations.
For example, certain roles such as truck drivers or heavy machinery operators may require drug testing due to the potential hazards involved. By conducting pre-employment drug testing, staffing firms can assess an applicant's suitability for these specific roles and make informed hiring decisions.
