Final answer:
The best demonstration of the organizational impact of a union avoidance strategy is increased flexibility in management decisions, as it allows for more control and quicker responses to changes without union involvement.
Step-by-step explanation:
The organizational impact of a union avoidance strategy is best demonstrated by C. Increased flexibility in management decisions. This is because without the presence of a union, management retains more control over workplace policies, procedures, and can respond more rapidly to changes. Union avoidance strategies are designed to maintain this flexibility by engaging employees directly and ensuring that their needs are met without the mediation of a union. Conversely, the other options like increased time on contract negotiation or increased risk of operational disruptions are actually impacts associated with having a union. Employers may use strategies to keep unions out of the workplace to avoid these potential issues and maintain greater control which can translate to more rapid decision-making.
