Using advisory levels in a travel policy
Many companies tie approvals to these levels. A policy might, for example, ask for a manager's approval before any trip to a Level 3 country, and allow Level 4 travel only with senior sign-off and a security plan. Our free travel policy template has a clause for this, and the duty of care checklist covers what to do before, during and after a trip.
