Per Diem

 
Per diem, meaning “for each day” in Latin, is a set amount of money an organization gives an employee each day to cover expenses while traveling for business. It can also be a payment for short-term workers who are paid a daily rate. Employees traveling for business incur additional expenses outside of travel costs, like lodging and meals, and many expect to be reimbursed for these. Employers are not legally required to reimburse employees for travel expenses, but it is considered good business practice.
