An employee complains every year about a small salary increase. A newer employee is receiving a significant salary increase based on merit. Which human resources activity justifies the larger salary increase?

Staffing decisions refer to the processes involved in recruiting, hiring, and assigning employees to roles within an organization. While staffing decisions are crucial for the overall workforce structure, they do not directly relate to salary increases based on individual performance. Therefore, they do not justify the larger salary increase in this context.

Training programs focus on developing employees' skills and competencies, which can enhance job performance over time. However, the existence of training alone does not account for immediate merit-based salary increases. Consequently, while beneficial for employee development, training programs do not provide a rationale for the disparity in salary increases.

Employee relations involve managing the employer-employee relationship and addressing workplace issues. While fostering good employee relations is essential for organizational culture, it does not directly pertain to the performance-based justification of salary increases. Therefore, it does not explain the larger salary increase for the newer employee.
