What are verified actions of tampering with or substituting a drug-test specimen treated as?

Verified actions of tampering with or substituting a drug-test specimen are treated as a refusal to test because such actions undermine the integrity of the testing process. When an employee intentionally alters or substitutes their specimen, it is considered an unwillingness to comply with the testing protocol, which is often viewed as a refusal to submit to the drug test itself. This standard reflects the importance of adhering to established procedures that ensure accurate testing and safety in the workplace. Treating such actions as a refusal helps maintain strict policies regarding drug and alcohol use among employees, reinforcing accountability and compliance within the organization.
