Private employers with less than 20 employees do not abide by the Act on Co-operation within Undertakings, but instead the stipulations of the Employment Contracts Act. The employer is not obligated to engage in negotiations; instead, the employer is required to give an explanation of the grounds for the lay-off, and its estimated extent, implementation, commencement and duration. If the lay-off concerns a number of employees, the explanation may be given to the employee representative or the employees jointly. Before the lay-off notice, the employer shall reserve the employees or their representative an opportunity to be heard concerning the explanation given (Employment Contracts Act, chapter 5, section 3).
Check the collective agreement that your workplace follows and the Act on Co-operation within Undertakings or the Church’s co-operation agreement to see what they say about the matter (only partially available in English).
