Under which condition can an employer conduct a drug test?

An employer can conduct a drug test primarily under specific conditions that ensure legal compliance and fairness in the workplace. One key condition is obtaining prior consent from the employee, which protects the employee’s rights and adheres to legal frameworks that govern workplace drug testing. This consent should be informed, meaning that employees should be aware that drug testing might be a part of their job conditions.

Additionally, conducting a drug test after an accident at work is another legally permissible circumstance. This helps maintain workplace safety and can be a critical part of assessing the circumstances surrounding the incident.

Thus, both scenarios mentioned—testing with the employee's consent and after an accident—outline the conditions under which an employer can legally perform drug testing. The combination of these two conditions justifies selecting the option that includes both possibilities.
