What action is prohibited by the NLRA against employees who refrain from union activity?

The National Labor Relations Act (NLRA) is designed to protect the rights of employees regarding their participation in union activities. The correct answer pertains to the specific actions that the NLRA prohibits against employees who choose not to engage in union activities.

The prohibition of unjust termination is significant as it implies that employees can not be fired for their choice regarding union involvement. While discrimination based on union membership is also a serious concern, it focuses on the treatment of employees based on their affiliation or non-affiliation with a union, rather than their choice to refrain from union activity.

Reprimanding employees for their non-involvement is directly tied to the freedoms allowed under the NLRA, emphasizing that employees should not face repercussions for choosing not to participate in union activities.

Thus, the NLRA's protections extend to all employees, ensuring that those who refrain from union involvement are not penalized or discriminated against for their decision. Therefore, actions like violence, which would be unrelated to union activity decisions, remain outside the scope of protection under the NLRA, reinforcing job security for non-participants in union activities.
