When employees are travelling, they are compensated for their expenses spent while away. To offset the risk that employees are abusing this priviledge and rewarding themselves with excess purchases at the Company’s costs, employers often require that these employees be paid a per diem rate per date. This per diem rate typically covers costs incurred related to routine travel, but not air fare or longer train trips which are separately compensated. It often typically covers food costs, but not hotel rates. Employees complete an per diem expense report which shows the days spent travelling and the standard per diem rate and are then compensated for their travel in this manner.
