An organization’s human resources department is responsible for a variety of functions. Human resource departments oversee employee payroll and tax filing as well as employee benefit and health administration. Human resources also manage legal compliance, maintain files and records, and oversee training and development. For many businesses, the various functions of the HR department are too comprehensive and complex to maintain in-house. Businesses that outsource HR functions receive several advantages that support the company’s bottom line. Among other reasons, manpower outsourcing is required when a firm needs to complete a task in which they don’t want to hire new employees, which would imply incurring added costs that can be avoided through outsourcing.
