The reason for this lies primarily with the provisions of the LSL. The law requires that a worker have been working 15 years in the same company and attain the age of 55 or have worked 25 years before he or she has the right to receive a pension.
究其原因，主要是勞基法規定，勞工必須在同一事業單位服務滿十五年、且年滿五十五歲，或是工作滿二十五年，才享有退休金請求權。
