The transition from the Fordist to post-Fordist techno-productive model has brought with it a noticeable labor flexibilization from which outsourcing is derived. Peripheral industry, such as the Colombian one that suffered a regression at the end of the last century, does not escape from this phenomenon. The present article seeks to establish the dynamics of fixed-term employment in the manufacturing industry, using information from the Annual Manufacturing Survey (AMS). The analysis found that the use of temporary employment since the 1990s increased at the expense of permanent employment, until reaching 41.4% in 2013; in the Boyaca region, although it has grown rapidly since the beginning of this century, temporary employment is only about 30%. Direct contracting exceeded indirect hiring, which does not contradict the persistence of the above mentioned trend that has predominated in the most relevant occupational categories of the industrial sector.
