Withdrawal
If at anytime a member withdraws from a retirement system (refunds accumulated deductions), upon rejoining a retirement system in the future, the member will come in as a new member, and their membership date will be as of the date of rejoining, not the date of their prior (refunded) starting date of service. This information is imperative to members who were hired before April 2, 2012 who are considering withdrawing.
