The pay or wages you earn for doing your job is called your salary. You might prefer your low-paying job to one with a higher salary because you have so much fun with your co-workers.
Salary comes from the Latin word salarium, which also means "salary" and has the root sal, or "salt." In ancient Rome, it specifically meant the amount of money allotted to a Roman soldier to buy salt, which was an expensive but essential commodity. Today, salt is an inexpensive purchase at the grocery store, and your salary is certainly to be paid in your country's currency.
