Final answer:
A staffing company can require employees to be tested for drugs if the customer insists on drug testing. The legality and enforceability of drug testing depend on various factors such as state laws, company policies, and job requirements.
Step-by-step explanation:
In general, a staffing company can require employees to be tested for drugs if the customer insists on drug testing. However, whether or not drug testing is allowed depends on several factors including state laws, company policies, and the nature of the job. Some states have specific laws regarding drug testing, while others allow employers to establish their own drug testing policies.
It is important to note that drug testing should comply with legal requirements, such as obtaining informed consent from employees and following proper procedures to ensure accuracy and fairness. Some jobs, such as those involving safety-sensitive positions or employees working with children, may have stricter drug testing requirements.
Ultimately, the legality and enforceability of drug testing in a staffing company will depend on the specific circumstances and applicable laws.
