Which statement regarding post-employment benefits is true?

Post-employment benefits, such as pensions, retiree healthcare, and other post-employment programs, are designed to provide support to employees after their employment has ended. The statement that these benefits accumulate over time is accurate because many post-employment benefits are based on factors such as years of service, salary history, or contributions made by the employer during the employee's tenure.

For instance, in a defined benefit pension plan, the amount an employee will receive upon retirement typically depends on the length of their service and their earnings prior to retirement. Consequently, the benefits become more substantial as the employee continues to work and fulfill the eligibility requirements.

The other options reflect misconceptions about how post-employment benefits function. The likelihood of payment, the ability to estimate these benefits, and the conditions under which they are provided vary greatly depending on the organization and the specific plan design. Therefore, the statement about these benefits accumulating over time stands out as the foundational truth in understanding post-employment benefits.
