This paper studies the effects of fixed-term contracts on workers. Specifically, the paper analyzes their impact on wages and on satisfaction levels. Regulations governing fixed-term and indefinite contracts in Colombia and the main labor reforms related to these two types of contract are analyzed. Women, young and low-educated workers, who work in small firms, in the private sector and in construction or manufacturing are most likely to have fixed-term contracts. In terms of wages, we found a significant raw and adjusted wage gap against workers with fixed-term contracts. Finally, we found, as expected, evidence that fixed-term contracts reduce the level of worker satisfaction.
