摘要： 竞业限制问题是正在制定中的《劳动合同法》应规范的内容之一。单位对劳动者再就业。进行的竞业限制行为和劳动者的忠实义务之间存在何种关系，他们各自和保守商业秘密之间的关系如何看待，以及竞业限制行为的理由、合法性条件如何确定等问题，是《劳动合同法》正确规范竞业限制行为不可回避的考虑因素。本文提出，劳动者的忠实义务和竞业限制条款是两个含义不同的概念，两者来自不同的法律目标：前者是劳动法律关系的特征所要求的，而后者则是在保护公共利益、保护劳动自由权和公平竞争原则之间寻求平衡的结果。在区分了相关的基本概念的含义之后，文章结合英法两国劳动法判例的分析，对竞业限制条款的有效条件、履行和相应的违法责任进行了阐述，并对我国《劳动合同法》中的竞业限制立法和相关司法提出建议。
