  • A daily payment made to workers hired on a day-by-day basis.
  • A temporary or as-needed work schedule, especially in healthcare.

Why Companies Use Per Diem

Businesses often provide per diem because it:

  • Simplifies expense reporting.
  • Reduces paperwork.
  • Gives employees spending flexibility.
  • Sets clear travel budgets.

Unlike reimbursement, employees usually receive a fixed daily amount instead of submitting every receipt.


Background & History

The phrase per diem comes directly from Latin.

  • Per means “for.”
  • Diem means “day.”

It has been used for centuries in legal, government, and financial documents.

Originally, governments and organizations used the phrase when calculating daily wages and travel expenses. Instead of tracking every meal or purchase, workers received one fixed amount for each day they traveled.

As international business expanded during the 20th century, companies adopted per diem policies because they were easier to manage than collecting hundreds of receipts.

Today, the term appears in:

  • Corporate travel policies
  • Government agencies
  • Military organizations
  • Hospitals
  • Schools
  • Universities
  • Consulting firms
  • Construction companies

Modern job listings also use per diem to describe flexible positions where employees work only when needed instead of having fixed weekly hours.
