Payroll periods, often referred to as pay periods, are the intervals of time in which an employee is paid for their work. These periods are typically measured in weeks, with most employers paying their employees on a bi-weekly or semi-monthly basis. The length of the payroll period can vary depending on the employer and the type of job. For example, some jobs may require employees to be paid on a weekly basis, while others may require payment on a monthly basis. Regardless of the length of the payroll period, it is important for employers to ensure that their employees are paid accurately and on time.
