Under the NLRA, which action is prohibited for employees trying to gain union support?

The action that is prohibited for employees trying to gain union support under the National Labor Relations Act (NLRA) is threatening coworkers. The NLRA is designed to protect the rights of employees in relation to union activities, ensuring that they can organize, form, join, and assist labor organizations without coercion or intimidation.

Threatening coworkers undermines this protection as it creates a hostile environment and can deter employees from exercising their rights to support or join a union. Such behavior is considered unfair labor practice because it can lead to an atmosphere of fear, directly impacting the ability of employees to freely choose whether or not to support union representation.

In contrast, discussing union matters and campaigning peacefully are protected activities under the NLRA, allowing employees to share their views and advocate for union support. Additionally, voting on union representation is a fundamental aspect of the unionization process and is also supported by the NLRA, ensuring that employees have a voice in determining their workplace representation.
