Which of the following scenarios would justify using short-term disability insurance?

Using short-term disability insurance is most relevant in a scenario where an individual is unable to work due to a severe injury. This type of insurance is specifically designed to provide financial support to employees who cannot perform their job duties due to a temporary disability or medical condition. The coverage typically replaces a portion of the individual's income during their recovery period, ensuring that they can manage their financial obligations while focusing on healing.

In contrast, taking a vacation, changing career paths, or receiving a promotion does not involve an inability to work due to health reasons and thus would not qualify for short-term disability insurance. These situations do not reflect a temporary disability that would prevent someone from fulfilling job responsibilities, which is the core purpose of this type of insurance.
