For-Cause Testing Checklist for Managers

Observe and document

Record clear, factual observations with time and location. Avoid assumptions and speculative language.

Escalate through policy route

Notify the authorised manager/HR contact and follow your documented response pathway.

Protect workplace safety

Reassign or remove from safety-critical tasks if risk indicators require immediate controls.

Arrange testing promptly

Use approved collection channels and chain-of-custody controls to preserve evidence quality.

Maintain confidentiality

Limit communications to those who need to know and avoid broad team discussion of individual cases.

Complete post-case review

Log decisions, outcomes, and process improvements for future manager training and governance.
