(1) The employer may summarily dismiss an employee if he or she is guilty of a gross breach of duty or other serious breach of the contract of employment.(2) The provisions of sections 15-1 and 15-4 shall apply correspondingly to summary dismissal.(3) If summary dismissal is unlawful, the court shall rule it invalid if so demanded by the employee. In special cases, the court may nevertheless, if so demanded by the employer, decide that the employment shall be terminated if, after weighing the interests of the parties, the court finds it clearly unreasonable that employment should continue. The court may also decide that the employment shall be terminated when it finds that dismissal is objectively justified.(4) An employee may claim compensation if the summary dismissal is unlawful. Compensation shall be decided in accordance with section 15-12, second paragraph.
