Which factor is NOT a typical source of stress for an officer's family?

The presence of family support during an officer's work hours is generally considered a positive factor rather than a source of stress. Family support can provide emotional stability and reassurance, helping to mitigate the stress that can come from the unique challenges associated with law enforcement. Families who understand the demands of an officer's job often play a crucial role in maintaining a healthy home environment, offering support and communication that can help alleviate some of the pressures experienced by the officer.

In contrast, the other options represent situations that might contribute to stress for the officer's family. For example, the presence of a gun in the home can lead to safety concerns and anxiety about potential accidents or misuse. High expectations placed on officers' children can create additional pressure, leading to stress as children may feel the need to perform exceptionally well. Avoidance by officers’ children might also stem from fear or misunderstanding of their parent's job, contributing to feelings of isolation or worry. Thus, family support during work hours stands out as a factor that does not typically contribute to stress.
