Salaries from WikiPedia:

A salary is a form of periodic payment from an employer to an employee, which may be specified in an employment contract. It is contrasted with piece wages, where each job, hour or other unit is paid separately, rather than on a periodic basis.

From the point of a business, salary can also be viewed as the cost of acquiring human resources for running operations, and is then termed personnel expense or salary expense. In accounting, salaries are recorded in payroll accounts.

While there is no first pay stub for the first work-for-pay exchange, the first salaried work would have required a human society advanced enough to have a barter system to allow work to be exchanged for goods or other work. More significantly, it presupposes the existence of organized employers—perhaps a government or a religious body—that would facilitate work-for-hire exchanges on a regular enough basis to constitute salaried work. From this, most infer that the first salary would have been paid in a village or city during the Neolithic Revolution, sometime between 10,000 BC and 6,000 BC.
