近年來，全球經濟受到交通運輸與資訊科技之發展及全球化的影響而產生巨變，導致現今業界中的競爭漸趨加劇。在現今國際化現象下所帶動之商業模式當中，與外國客戶、同事及長官之間的交易往來、會議簡報、溝通諮詢等情況愈趨普遍。因此，職場英語能力這議題仍受到相當的關注。 然而，台灣人的母語仍非英語，與他人使用英語溝通的過程會產生語言焦慮感，其影響其個人之工作績效表現並更進一步地影響其就業力。此外，如個人有考取語言能力測驗，其分數高低將影響個人之語言焦慮感及就業力。
本研究將語言焦慮作為自變數、將就業力作為依變數，並以語言能力作為調節變數。其目的為探討語言焦慮與就業力之間的關係及語言能力的調節作用。本研究採量化方式進行，並以線上電子問卷方式發放給556名在科技業服務之台灣員工，共249份為有效問卷。本研究採用統計軟體SPSS第20版與AMOS第18版進行問卷分析。
最後，其研究結果顯示語言焦慮感與就業力之間具有負向關係，且語言能力於兩者間具有正向之調節作用。
