Surprisingly, many people with disabilities stay at Samsung Electronics until retirement

‌If they set their minds to it,
once they pass their 50s, they usually have to prepare to leave the company, whether voluntarily or involuntarily.
However, due to mandatory employment quotas for the disabled and awareness regarding disability discrimination, large corporations do not force them out aggressively.
Instead, as long as they don't cause major issues, they allow them to work until the official retirement age, much like civil servants.
