Short-term & Long-term Disability Insurance

Employer-sponsored or individually purchased policies that pay a percentage of your salary while you cannot work due to a covered medical condition.

Typical timeline: STD: payments often start after a 7–14 day elimination period. LTD: typically begins after 90–180 days of continuous disability.

This page is a dedicated, search-friendly version of the same checklist on the main disability benefits guide. Progress checkboxes sync in your browser only.
