有限公司轉左股東，是否追唔到份糧？

唔係, 因為當時係公司請你, 聘請你的是那個無良僱主, 當時是他名下公司請你, 雖然現在賣左盤俾其他人, 但勞工處仍會聯絡新的股東, 追討你份糧, 所以唔需要擔心.

除非佢開一間新公司而棄用舊公司, 否則不論佢將股東和公司名轉幾多次, 在公司註冊處仍有他的記錄, 因為轉股東和公司名都需要向公司註冊處申請, 由公司註冊處向高院呈交, 先可以改架
舊的無良僱主係有可能置身事外架, 因為新的股東同舊老細收購公司股份時, 會簽署有關債務轉移文件, 如註明公司資產及債務全數轉移給新股東, 他就可以不用負責, 這個主要決定在收購公司協議內.

As you are employed by a limited company (A), a separate legal entity, your salary is still payable by 'A' even the directors and shareholders of it have been changed. The new directors are still answerable to your claim on outstanding salary in law. If the limited company is unable to pay you, it will be wound up. The cash on assets sold will then be used to pay you the salary in priority.
