Abstract
Abstract. This paper uses the methodological scheme of contingency tables to explore polarisation in the Polish labour market. We use a large database of online job offers published on selected Polish job portals in the period 2017-2019, whereas most of the studies on the polarisation hypothesis are based on employment data. The main advantage of our microdata is the use of information on the required skills of the vacancy. The contingency table allows us to generate clusters of vacancies whose attributes tend to appear jointly. The study reveals that office skills do not offer a particular advantage in an automated labour market, while information and computer technology skills and communication skills seem to have a shield effect in such an environment. In addition, a cluster of transversal skills (self-organisational, technical and interpersonal skills) constitutes an important requirement for most job offers. These skills should be widely developed within the educational system ...

El trabajo emplea el esquema metodológico de las tablas de contingencia para explorar la polarización en el mercado de trabajo polaco. Usamos una amplia base de datos de ofertas de trabajo online publicadas en destacados portales de empleo polacos en el periodo 2017-2019, a diferencia de la mayoría de los estudios sobre la hipótesis de polarización, que están basados en datos de empleo. La principal ventaja de nuestros microdatos es el uso de información sobre las competencias requeridas de la vacante. La tabla de contingencia nos permite generar clusters de vacantes cuyos atributos tienden a aparecer conjuntamente. El estudio revela que las competencias de oficina no ofrecen una ventaja particular en un mercado de trabajo automatizado, mientras que las competencias de tecnologías de la computación y la información parecen tener un efecto protector en dicho entorno. Además, observamos que un cluster de competencias transversales (competencias de auto-organización, técnicas e interpersonales) constituye un requisito importante para la mayoría de las ofertas de trabajo. Estas competencias deberían ser ampliamente desarrolladas en el sistema educativo, en sus diferentes niveles.
