Long-term disability refers to a condition where an individual is unable to work for an extended period, typically due to illness or injury. This situation can significantly impact a person's financial stability and quality of life. Long-term disability insurance is designed to provide income replacement during this time, helping individuals manage their expenses while they recover. Eligibility for long-term disability benefits often depends on the specific terms of an insurance policy or employer-provided plan. Many policies require a waiting period before benefits begin, and they may cover a portion of the individual's salary for a set duration, often until retirement age or until the individual can return to work.
