The definition of a collective dismissal refers to a certain number of employees in comparison to all employees including full-time employees with open-ended employment contracts, fixed-term and part-time employees. The definition includes all employees who are going to become redundant within the period of 30 days (Supreme Court decision no. VIII Ips 90/2013). The number of redundant employees covers persons whose employment contract is  terminated as well as employees whose present contracts is terminated, but to whom the employer has offered a new employment contract under new conditions. Not included are the employees whose employment contracts are terminated by mutual agreement or who continue working for an employer under new conditions without termination of employment contract (Supreme Court decision no. VIII Ips 178/2012).
