Questions related to periodic income earned through employment, especially in predefined amounts such as might be stipulated in a contract. This tag should be used in contrast to questions about wages, which are typically earned at a defined *rate* per time period rather than in defined total amounts.
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 view of running a business, salary can also be viewed as the cost of acquiring and retaining human resources for running operations, and is then termed personnel expense or salary expense. In accounting, salaries are recorded in payroll accounts.
