Which body manages unfair labor practices?

The Employee Relations Board (ERB) is the correct answer because this body is specifically tasked with overseeing issues related to unfair labor practices. The ERB is established to administer and enforce labor laws, ensuring that employees are treated fairly in relation to their labor rights. It conducts investigations, holds hearings, and makes determinations regarding allegations of unfair labor practices, thereby helping to maintain a balanced and lawful working environment.

The other bodies mentioned, such as the City Council, the Human Resources Department, and the Labor Relations Division, have various roles within the organizational structure but do not primarily focus on managing unfair labor practices. The City Council is involved in legislative functions and local governance, while the Human Resources Department typically deals with employee management and organizational policy rather than direct enforcement of labor laws. The Labor Relations Division may deal with aspects of labor negotiations and contracts but does not serve the specific purpose of managing unfair labor practices as the ERB does. Thus, the ERB's specialized role makes it the appropriate entity for addressing these issues.
