Abstract EN:

With the successful of the notion informal [unofficial] in the socio-economic analysis of developing countries since the beginning of the 1970's, the notion of informal sector is used to refer to a very heterogeneous group of economic players and micro-businesses (one person or family business) generally set aside of labour laws, who are not registered by the administrative services and hardly benefit from any form of social welfare, judicial or administrative protection on the professional level. Moreover, the informel [unofficial] sector is defined as opposed to the "formal" [official] sector. Also victims of economic insecurity, one might say that informal [unofficial] players are to a large extent victims of the lack of job security. However, in a national socio-economic context characterized by few welfare transfers, almost endemic unemployment and underemployment, a buying power still considered unsuited for the cost of living, etc. , it is difficult to imagine that workers of the modern sector (generally more protected than the those in the informal sector) are safe from a lack of job security. This is at the origine of the idea of there being several kinds of job insecurities in Sengal, among others "formal" and "informal". What singles out our approach of the lack of job security is that it seeks to superpose the objective dimensions of the issue (professional instability, professional dissatisfaction, etc. ) to the sunjective dimensions (perception, feeling of precariousness).
