“…Most would agree that a country’s capacity for building a knowledge-based economy relies less on traditional resources such as capital and labor for wealth creation and growth, and more on the intellectual capital of knowledge workers who have the skills and capacities for contributing innovative products, services, and processes that create value to the company and client (De Beer, 2015; Du Toit, 2014; Sutherland, Naidu, Seabela, Crosson, & Nyembe, 2015; Tchamyou, 2016). Therefore, it is not surprising that organizations demand of knowledge workers to be highly adaptable to changing business conditions and to stay relevant by proactively managing their employability (Sutherland et al., 2015).
