In the paper the authors analyze the effect of the employment contract for a definite period of time on the flexibility of the employer and on the safety of the worker. They try to find a common denominator of the two contrasting requests through the concept of flexicurity. Although they are considered to be nonstandard forms of employment and the phenomenon of them being atypical nowadays can be seen only as an anachronism because the number of such contracts is in constant growth, the reason for this growth is obvious. These contracts are considered to be a good instrument for cutting the employer’s expenses, which optimizes his/her competitiveness on the market. At the same time this jeopardizes the worker’s safety at the labor market. In order to surpass these difficulties legislative interventions have been done on the level of the European Union. The authors analyze the effects of the Directive of EU about work at a definite period of time on the position of workers employed for a definite period of time. They also compare these effects on labor legislation of the Republic of Croatia and the Federal Republic of Germany. By comparing and analyzing solutions de lege lata, they suggest solutions de lege ferenda.
