Workplace benefits are genuinely valuable, and turning them down isn't the point of this post. But treating them as "I'm covered, full stop" is where people get caught off guard. Group coverage was designed to be a baseline for a large pool of employees, not a personalized plan for your specific situation.
Group life insurance: rarely enough on its own
Most group life plans provide something like one or two times your salary — a fraction of what a proper income-replacement calculation usually comes to. Coverage above a certain amount often requires evidence of insurability, meaning it isn't automatic even within the group plan.
Group disability insurance: capped and temporary
Group long-term disability typically replaces a percentage of income, often capped at a maximum monthly benefit regardless of what you actually earn. Many plans only cover you if you can't work in "any occupation," not specifically your own — a much higher bar to meet than it sounds.
It doesn't follow you
The biggest gap isn't in the coverage amount — it's portability. Group coverage typically ends the day you leave the job, whether that's your choice or not. That's often the worst possible time to be shopping for new coverage, since age and health changes since you were first hired can make individual coverage more expensive, or in some cases harder to qualify for.
The fix isn't to cancel group coverage — it's to supplement it
Group benefits are a reasonable baseline. Individual life, critical illness and disability coverage layered on top closes the specific gaps — and stays with you regardless of what happens with your job.
