Fixed contract for a specific work in the construction industry: fixing and developing the image of an special employment contract in the digital age

El contrato fijo de obra, estandarte del sector de la construcción, es una figura controvertida en su naturaleza, que representa como acaso pocas otras el choque entre la categorización jurídica y la realidad negocial y del mercado de trabajo, avalada ésta, en principio, por el fin de tutela del trabajador. Con antecedentes en la Ordenanza de la Construcción, Vidrio y Cerámica del año 70 y anclaje en la LSC y en el ET, entre otras normas, ha sido atendida en el nivel negocial estatal ininterrumpidamente, destacando su cuestionada condición de modulación del contrato de obra o servicio determinado, refrendada no obstante por nuestro Tri­bunal Supremo, y el singular régimen de duración del contrato. Un tratamiento jurídico que deja tras de sí un reguero de incertidumbres, que conjuntamente con los pronunciamientos judiciales, son abordadas en el presente estudio.The fixed contract for a specific work in the construction industry, a flagship of this sector, is a controversial figure in its nature, which represents, as perhaps few others, the clash between legal categorisation and the reality of the business and labour market, the latter backed, in principle, by the aim of protecting the worker. With antecedents in the Construction, Glass and Ceramics Ordinance of 1970 and anchored in the LSC and in the ET, among other regulations, it has been uninterruptedly dealt with at the state negotiating level, highlighting its questioned condition of modulation of the contract for a specific work or service, endorsed however by our Supreme Court, and the singular regime of duration of the contract. A legal treatment that leaves behind a trail of uncertainties, which, together with the pronouncements of the courts, are addressed in this study
