--- - |2 Abstract In this article, I aim to cast light on the arguably indeterminate phenomenon of the global labour market (GLM) by placing the focus on an industry that has sometimes been perceived as epitomizing homogeneity and ‘world flatness’ in its deployment of geographically dispersed knowledge workers, that of international software development. Engaging in a sanguine analysis of this industry with reference to an empirical study of outsourcing to Ukraine it is revealed that labour markets servicing ICT (Information and communication technology) are subject to deep, if fluctuating, social stratifications. With reference to the notion of the global value chain (GVC), the significance of factors such as knowledge, language, citizenship and age as labour market differentiators for knowledge work is brought to the fore. - 'Global Networks, EarlyView.
