在20世紀後半及21世紀，工作者見證了新階段的職業發展，稱之為不受單一組織「捆綁」或「規範」的多樣性職業或是無疆界職業。越南身為一個開發中國家，在經濟發展相當迅速，同時也吸引了越來越多的國外投資者的情況下，年輕且受教育的勞工為主要勞動力來源。由於以上這些原因，本研究為了探討無疆界職業與其他重要的層面如就業適應能力、就業能力、以及就業滿意度等等之間的關係。
本研究側重於某些主要產業，研究受測者來自於越南城市中的公司。樣本於電子郵件、社群媒體內隨機抽樣回收。總發放超過300 份問卷中，回收了240 份。本研究採用了皮爾森相關係數與線性回歸，以利分析變數間的關係
本研究的分析結果顯示了兩個主要發現，首先是無疆界職業與就業能力、就業滿意度有顯著的正向關係。次者，這些關係會受到就業適應力的中介效果而部分影響。這些發現有助於提高相關領域文獻、管理者、員工本身等實務上的應用含義。此外對於未來的研究建議也能見於本研究。

The last haft of twentieth and twentieth first century witness a new stage of career development called protean career or boundaryless career which is no longer “bound” or “regulated” by one organization. In the context of Vietnam as a developing country whose economy is growing rapidly and attract more and more foreign investors, young educated employees are the main labor force. For these reasons, this study is going to examine the relationship of boundaryless career and other important constructs such as: career adaptability, employability and career satisfaction.
The research focuses on certain main industries, participants come from several companies in cities of Vietnam. The samples are collected randomly via email, social network. Over 300 questionnaires were distributed and 240 were sent back. Pearson’s correlation and Linear regression are applied to analyze the relationship among the variables.
The result of analysis revealed two main findings. First, there are significant positive relationships of boundaryless career with employability and career satisfaction. Second, these relationships are mediated partially by career adaptability. These finding help raise the practical implication for the literature as well as managers and employees themselves. Also, suggestions for future research are also addressed.
