Change of Employer and Preservation of Employment: Serbian Experience in Light of European Law

Protection of employees in the event of a change of employer in Serbia was first regulated by the Labour Act (2005). This was a result of the harmonization of Serbian legislation with Council Directive 2001/23/EC, while the effect of the European Court of Justice jurisprudence was negligible. Protection is guaranteed regardless of whether the company identity has been preserved or not, thereby making it more favourable than the European concept of transfer of undertaking. Nevertheless, the relevant provisions of the Labour Act have often been evaded in practice, especially when it comes to the application of the principle of preservation of employment. This was facilitated by the content of certain legal provisions. There is a notable need for their improvements, in order to enable employees to continue to work for the transferee under the same working conditions and be protected from dismissals exclusively or predominantly motivated by the change of employer

A network flow approach to a common generalization of Clar and Fries numbers

Clar number and Fries number are two thoroughly investigated parameters of plane graphs emerging from mathematical chemistry to measure stability of organic molecules. We consider first a common generalization of these two concepts for bipartite plane graphs, and then extend it to a framework on general (not necessarily planar) directed graphs. The corresponding optimization problem can be transformed into a maximum weight feasible tension problem which is the linear programming dual of a minimum cost network flow (or circulation) problem. Therefore the approach gives rise to a min-max theorem and to a strongly polynomial algorithm that relies exclusively on standard network flow subroutines. In particular, we give the first network flow based algorithm for an optimal Fries structure and its variants
