1. As to the misapprehension of legal principles as to ordinary wages and incomplete deliberation

(a) In order for a certain wage to be included in ordinary wages, it must be paid periodically, uniformly, and fixedly.

The wage for which whether to pay or pay is determined by evaluating the work performance of a worker during the period subject to payment is generally denied, but if the minimum amount of payment has been determined, such as paying a specified amount, even if it is rated below the lowest amount of payment for work performance, the minimum amount of wage is fixed.

In addition, where a worker determines whether to pay or pay a specific amount of wages in the year concerned according to the worker's work performance in the year concerned, since the payment or amount of the wages is fixed in the year concerned, the wages are fixed in the year concerned.

(see, e.g., Supreme Court en banc Decision 2012Da89399, Dec. 18, 2013). (B)
