2. The parties' assertion

A. The gist of the plaintiffs' assertion (1) The defendant Corporation calculated legal allowances except for the allowances of the nature of ordinary wages, and paid retirement allowances to the plaintiffs based on this.

Therefore, Defendant Corporation is obligated to pay the difference between the amount of money and the retirement pay paid to the Plaintiffs by re-fixing retirement allowances based on the legitimately calculated ordinary wages.

In addition, according to the Ministry of Public Administration and Security guidelines, even though Defendant Corporation has to pay employees who have served for not less than 10 years in addition to 50% of retirement allowances, Defendant Corporation did not comply with the above regulations while paying retirement allowances to the Plaintiffs. Defendant Corporation is obliged to pay additional amounts equivalent to 50% of retirement allowances which are fixed based on legitimate ordinary wages as above.

However, the plaintiffs seek additional payment of the amount equivalent to 20% within their scope.

The total amount of retirement allowances to be paid by the plaintiffs according to the above calculation is the amount claimed.
