Business-management studies have shown that human capital is the basis for creating value. In the past, most attention was given to material assets; in today's marketplace, immaterial assets are what represent the greatest value in organisations. Companies set themselves apart on the basis of flexibility, innovation, and time-to-market. Those are all aspects that rely on the organisation's internal resources and capabilities.
By acknowledging the importance of human capital and acting accordingly, organisations perform better than others in their sector. The wellness of employees and good working conditions ensure lower absenteeism and better performance, and, therefore, continuity.
