Final answer:
A company cannot prohibit its workers from making comments on social media if the content is aimed at prompting coworkers to take group action to correct working conditions, as this is considered protected concerted activity under the National Labor Relations Act of 1935. Therefore, the correct option is B.
Step-by-step explanation:
According to the National Labor Relations Board, a company cannot prohibit its workers from making comments about the company on social media if the messages are prompting coworkers to take group action to correct working conditions. This principle is rooted in the rights provided by the National Labor Relations Act of 1935 backed by the decision of the Supreme Court in NLRB v. Jones and Laughlin Steel. Employees' rights to organize and engage in collective bargaining are protected, and this includes the ability to discuss and seek improvement in work-related issues.
It is important to note that the NLRB protects employees when they are engaging in what is known as "protected concerted activity," which can include social media posts that are part of a dialog among coworkers about improving terms and conditions of employment. However, social media posts that are discriminatory, threatening or reveal trade secrets may not be protected. Always remember that though the First Amendment protects free speech from government censorship, this protection does not extend to all forms of speech in the workplace.
