Employment reduction must be assessed at the factory level, not individual job or department level, for early pension eligibility.

The Supreme Court allowed the plaintiff's cassation appeal, overturning the social insurance office's refusal of an early pension. The office had denied benefits because the plaintiff's specific job was converted to a contract rather than eliminated, arguing only a fraction of her workday was reduced. The court ruled that the legal concept of employment reduction must be evaluated for the entire factory, not limited to the specific position or department. Consequently, the reduction of the plaintiff's full-time equivalent status constituted a valid ground for the pension under the relevant regulation.
