• A. as an activity in which two or more employees engage in conduct for the purpose of collective bargaining or mutual aid or protection
• B. an activity by a single employee addressing safety concerns
• C. a management-led demonstration
• D. a private complaint by an individual employee

Answer: (A)

Under the NLRA, concerted activity is actions by two or more employees taken for the purpose of collective bargaining or mutual aid or protection. The defining feature is the group element, not a lone employee. The option that directly mirrors this language—two or more employees engaging in conduct for the purpose of collective bargaining or mutual aid or protection—best fits the statutory definition and represents protected activity when employees join together for workplace concerns.

An activity by a single employee addressing safety concerns lacks the required two-person element, so it isn’t concerted by the statute (even though it may be protected in other contexts if it becomes part of a broader joint effort). A management-led demonstration isn’t employee-initiated concerted activity and falls outside the protective scope. A private complaint by an individual employee is likewise not concerted activity, as it involves only one person.

So the correct choice is the one that specifies two or more employees engaging in conduct for the purpose of collective bargaining or mutual aid or protection.
