1. The defendant shall pay to each of the plaintiffs 26,897,070 won and 20% per annum from December 15, 2013 to the day of full payment.

From September 2, 2009, the plaintiffs provided labor under employment of the defendant who operates the clothing manufacturing business ("D") and retired on November 30, 2013. The facts that the plaintiffs' wages not paid by the defendant during the above period are 22,281,080 won, and retirement allowances are 4,615,90 won, respectively, do not conflict between the parties.

Therefore, the defendant is liable to pay each of the plaintiffs 26,897,070 won and damages for delay calculated at the rate of 20% per annum from December 15, 2013 to the date of full payment.

Thus, the plaintiffs' claims are accepted on the grounds of all the reasons.
