How many enterprises could weather this is a question of real concern. For this reason, the new system allows employers five years to transfer sufficient funds into their retirement reserve funds to cover the benefits due to workers to whom the old system still applies. To preserve their seniority, workers under the old system will still remain tied to their original jobs and not be able to move.
為此，新制已放寬要求雇主於五年內足額提撥選用舊制之勞工退休準備金，然而為了保存既有年資，新制實施後，已有舊制年資的勞工，還是得被綁在原來的企業，動彈不得。
