Hi Tanya,
I'll send you ours directly. You'll see it takes a somewhat open-ended approach in which all "reasonable expenses incurred for attending meetings or other TSSA business" are reimbursable. Some aspects are addressed in specific terms (e.g., maximum tip percentage, mileage distance calculation, business class flights, alcohol exclusion) but we leave many things to the judgment and discretion of directors and those administering the policy since it's difficult to think of everything in advance.
