In order for a collective agreement entered into by an undertaking to be valid, its approval at a general meeting (conference) of employees is required.
The collective agreement shall be approved by a simple majority vote at a general meeting at which at least half the employees of the relevant undertaking participate.
If it is impossible to convene a general meeting of employees due to the large number of employees employed by an undertaking or due to the nature of work organisation, the collective agreement shall be approved by a simple majority vote at a conference of employee representatives at which at least half of the employee representatives participate.
The validity of a general agreement does not require its approval.    _{Your Comment}
