It takes about six months for your MPI health insurance to begin once you start working and have not participated before, or have not participated in the health plan in a while. Your participation is not dependent on your union paperwork or the status of your union account. For your initial participation, you need to accrue 600 hours during a qualifying period; once you’ve accrued the allotted hours there is a two-month processing period before your benefits are active. During that time, you should receive the MPIPHP enrollment packet, which needs to be filled out and submitted.
