Secondary labour markets usually involve job positions with forced flexibility and non-standard working conditions (part-time contracts, fixed-term contracts, work without a contract). They are characterized by no advancement prospects or opportunities for further education, exhausting physical work with inadequate wages and job insecurity, and a frequently long and tiring commute. The working conditions in this sector of the labour market often contribute to marginalization and then to the social exclusion of those who happen to be caught long term in this sector of the labour market instead of preventing and saving them from the risk of marginalization and social exclusion. One of the ways in which secondarization occurs is the universal introduction of part-time contracts in a particular sector of the labour market which then becomes an involuntary trap of underemployment, underpaid wage, insecurity and discrimination. The profession of cashier in foreigner retail chains is an example of such a development. This qualitative study shows the step by step degradation of the employment conditions in this sector and how the lives of women and men working in the sector have deteriorated. At the same time, the condition and status of the profession overall are declining. This phenomenon is referred to as the "secondarization" process, Marcel Tomášek, Radka Dudová., and Obsahuje bibliografii
