MMC Benefits Handbook
When Coverage Begins
Your coverage will be effective on the first day you are Actively-At-Work on or after your date of hire.
What happens if I am not at work on the day my coverage is supposed to start?
If you are not Actively-At-Work on the day your coverage is supposed to begin, your coverage will be effective on the first business day of eligibility when you are Actively-At-Work.
