The first deduction holiday for 2017 is already here. Because deductions for health & welfare occur 4 times per month, months with 5 pay periods produce a "deduction holiday". December 2016 had 5 Saturdays, so the first deduction holiday of 2017 will be Jan 10th. Because of open enrollment changes a higher number than usual are in "catch-up" status. See link below to FAQ - health & welfare deductions - for more details.
If you were hired before January 1, 2010 and you retire, you can choose to continue your medical benefits (including prescription drug coverage) under the Plan. You are also eligible for life insurance and voluntary retiree dental coverage through Delta Dental.
When you retire, you are no longer eligible for short-term disability (STD), long-term disability (LTD) or accidental death and dismemberment (ADD) coverage.
You need to make monthly premium payments to receive coverage when you retire. In most cases, your premium payments are automatically deducted from your pension check. For more information on medical coverage after retirement, see "If You Retire" on the Life Events page.
