An employer who plans to have collective dismissals or to shut down a company has to submit relevant information to the public authorities.

In the event of collective dismissals, the Norwegian Labour and Welfare Administration (NAV) has to be notified 30 days before the planned collective dismissals (at least 10 dismissals within 30 days). Employers are required to notify public authorities 'at the earliest opportunity'. The employees' elected representatives may comment on the notification directly to NAV.

The notification should be the same as the one given to the employees, stating:

• the grounds for any redundancies, 
• the number of employees who may be made redundant, 
• the categories of workers to which they belong,
• the number of employees normally employed, 
• the groups of employees normally employed,
• the period during which such redundancies may be effected, 
• proposed criteria for selection of those who may be made redundant, 
• proposed criteria for calculation of extraordinary severance pay, if applicable.

Projected collective redundancies shall not come into effect earlier than 30 days after NAV has been notified.
