This work is focused on aspects of the general clauses used by the legislator in the Act on Collective Redundancies of 2003, i.e. reasons not attributable to an employee and their exclusivity. The first clause covers all cases of termination of an employment relationship that are caused by circumstances affecting the employer or independent of the parties to the employment relationship. On the other hand, “exclusivity” of the reasons not attributable to an employee is confirmed if circumstances not attributable to the employee and the way of performing employment relationship duties thereby constitute the original cause of a definite termination or a notice of change. Analysing the scope of application of the said indeterminate phrases, the author also refers to the principles of community life.
