Do I receive plan service credit for my period of military service?
Yes, the retirement plan will treat your time of military service as if you had continued to work for your employer. You will receive service credit for the entire period of absence for the purposes of plan eligibility, vesting, and service required to receive company contributions. Qualified military service is not treated as an interruption in employment for purposes of the break-in-service and vesting rules, nor for the accrual of benefits.
For example: Joe worked for the entire years of 2015 and 2016 and was away during all of 2017 for uniformed service. Upon his return to employment on January 1, 2018, Joe will have three years of vesting service: 2015 and 2016 (years of employment) and 2017 (year of uniformed service). This is the same vesting that Joe would have attained had he remained actively employed throughout those three years.
