1、sack用于口語，是俚語（相當于漢語中說“炒魷魚”）比方說：The coach sacked Joe because he never came to practice on time.教練把喬開除了，因為他從不按時來參加訓練。口語中也常說 (sb.) get the sack 和 give sb. the sack表示“解雇”、“炒魷魚”。2、fire是口語用語，指斷然地突然解雇，多見用于美國英語，比方說：He fired his clerk one day in a bit of anger but the next day he called him back.有一天他憤怒之余將雇員開了，不過第二天他就打電話讓他回來。
