Which of the following factors could contribute to workplace stress?

High workload and tight deadlines are significant contributors to workplace stress for several reasons. When employees face heavy workloads, they may feel overwhelmed by the sheer volume of tasks they need to complete, leading to feelings of anxiety or burnout. Tight deadlines further exacerbate this stress, as employees often feel pressure to deliver results quickly, which can affect their ability to maintain quality in their work. This combination of high demands and limited time can create an environment where employees feel constantly rushed and unable to manage their responsibilities effectively, ultimately impacting their mental health and job satisfaction.

In contrast, the other factors listed do not typically contribute to workplace stress. Excessive breaks may actually reduce stress by providing employees time to rest and recharge. Ample opportunity for advancement often serves as a motivational factor, encouraging employees to engage positively with their work. Similarly, friendly interactions between coworkers foster a supportive environment, which can alleviate stress rather than increase it.
