Supplemental Insurance

Beyond your core medical coverage, ONI offers company-paid protection plus optional plans you can choose to fit your life. Some are paid entirely by ONI; others you can elect and pay for at group rates.

  • Life Insurance and AD&D – company-paid basic coverage, with optional supplemental coverage for you and your family.
  • Short-Term Disability – company-paid income protection for shorter absences.
  • Long-Term Disability – company-paid income protection that picks up where STD ends.
  • Critical Illness Insurance – a lump-sum benefit if you are diagnosed with a covered illness.
  • Accident Insurance – a set benefit based on the injury and treatment you need.
