Yes, it does. If you leave your job, for example, you will cease to be eligible for risk benefits for death and disability in the 2nd pillar. Your retirement assets will be transferred to a vested benefits account. To ensure that there are no gaps in contributions to old-age and survivors' insurance (OASI), you should register with the OASI compensation office and pay the minimum contribution each year, unless you are married and the minimum contribution is paid via your spouse.
