The short answer
Yes—post orders should be updated when the property, risk, systems, schedule, or client requirements change. Effective orders are controlled operational documents, not a one-time attachment that remains unchanged for years. Changes may follow an incident, construction phase, new tenant, gate or alarm replacement, staffing change, revised emergency plan, or a recurring issue identified in reports.
What to know
Use a formal change process. The client and Arrow should identify who has authority to request and approve revisions. Each update should show its effective date and version, explain the new instruction, identify affected posts or shifts, and be distributed to every assigned and relief officer. Supervisors should confirm understanding through a briefing, acknowledgement, practical review, or training when the change is significant. Obsolete copies should be removed so officers do not receive conflicting directions.
Urgent temporary instructions can be issued through an authorized communication channel, but they should be documented and incorporated into the controlled version if they continue. No client employee should casually direct an officer to perform duties outside the contract, training, law, or safe operating scope. Ask Arrow how it stores orders, records officer acknowledgement, and verifies compliance. The contract should also explain when a scope change affects staffing, equipment, price, or insurance and requires a signed change order.
