Concerted activity 协同活动

〈美〉（劳动法）指雇员涉及工资或劳动条件的协同活动。此类活动受《全国劳资关系法》〔National Labor Relations Act〕保护，雇主不能借此处分或解雇雇员。典型的受保护的协同活动包括筹组或讨论筹组工会，某一雇员从另一雇员处寻求工会保护，但协同活动并非一定涉及工会，未参加工会的雇员为改善劳动条件在工作场所的活动也应认为是受保护的协同活动。

Protected Concerted Activity is a legal term used in labor policy to define employee protection against employer retaliation in the United States. It is a legal principle under the subject of the freedom of association. The term defines the activities workers may partake in without fear of employer retaliation. In countries where there is relatively robust employee dismissal protection, the protection of protected concerted activity is less of a distinct legal issue. In liberal market societies like the United States, where it is comparatively easy for an employer to fire an employee, the issue of protected concerted activity has become an important employment protection. 以下为相关例句，可供参考：

例句1

Generally speaking, there is protected concerted activity when two or more employees act together to improve their terms and conditions of employment, although it is (on rare occasions) possible for conduct to be so egregious that it becomes unprotected. Employees have a right to advocate in this manner even where there is no union involved.

一般来说，当两个或两个以上的雇员一起行动以改善他们的雇佣条款和条件时，就有了受保护的协同活动，尽管（在极少数情况下）这种行为可能很恶劣以至于不受保护。即使没有工会参与，员工也有权以这种方式进行倡议。

例句2

At times, protected concerted activity has extended to individual employees; for example, when an employee speaks individually to his or her employer on behalf of him or herself and one or more co-workers about improving workplace conditions. An individual employee who seeks to enforce a collective bargaining agreement will generally be deemed to be engaged in concerted activity.

有时，受保护的协同活动延伸到个别雇员；例如，当一名雇员代表他或她自己以及一名或多名同事单独与他或她的雇主商讨改善工作场所条件时。寻求强制执行集体谈判协议的员工个人通常被视为参与了协同活动。
