Final answer:
Supervisors with political skills effectively garner support and cooperation to accomplish goals, and this is true. Their skills are valuable for navigating delicate situations, executing policies, and mitigating political pressures from stakeholders.
Step-by-step explanation:
Supervisors with good political skills are indeed known to achieve objectives by rallying support, cooperation, and effort from others. This assertion is true. In the realm of politics and leadership, whether in government or within an organization, the ability to navigate complex social situations and influence others is crucial. Leaders and politicians often lack the specific expertise to implement public policy single-handedly and may also face controversial decisions that put them under political pressure from various stakeholders. Therefore, they must negotiate and collaborate with advisors, interest groups, or local politicians to align efforts and shape the outcomes effectively.
