Employees are ready to complete work tasks and contribute to overall productivity only if they are deeply motivated and have reasons that are driven primarily by personal interests to meet the requirements of the company. Therefore, they initiate a series of business activities and carry out business tasks on their own initiative, contributing to the company's business excellence and its successful business results. The goal of human resources department is to invest in their education and develop their working competencies in order to contribute to the development of a system that includes organizational efficiency, quality, innovation and responsibility towards the customer, that is, integrates all ways of achieving competitive advantage. After motivation for start-up business activities and management's investment in stronger development of employees business skills and competences, they acquire narrowly specialized knowledge that will then be applied to their jobs, improving the overall work productivity of the company. For their employees, upon achieving excellent results, they are given incentive compensation for their work outside the external administration, which can be direct (increase pay, bonus and incentives) and inevitably (specializations, study trips and the like). Public work is determined because public service is a specific organizational dimension where purely public interests are pursued and when there are no services, they need not generate profit.
