Stability Period in Employer-Sponsored Plans

Employers usually use a measurement period to trace whether employees meet full-time needs. Once eligibility is confirmed, the stability period ensures that coverage continues regardless of minor fluctuations in hours.

How Stability Period Protects You Financially
