The Interstate Hours Trap — How Working Across State Lines Can Cost You Two Pensions
Pay & Benefits
Thirty-seven years. Three unions. Thirteen states. One pension at the end. I should have had more. I lost contributions to two separate pension funds because nobody explained interstate hour reciprocity to me when I was young enough for the explanation to matter. I am writing this so you do not learn the same lesson the same way.
When you work out of your home local in another jurisdiction, the hours you earn go into the pension fund of the local where you are working — not your home fund. That is standard and most members understand it. What most members do not understand is the reciprocity agreement, or lack thereof, between those two funds. Some pension funds have full reciprocity agreements — if you earn hours in Local X, those hours are credited to your home fund pension calculation. Many do not. If your home fund and the host fund do not have a reciprocity agreement, those hours sit in a separate fund that you may not fully vest in if you were only there for a short period.
The vesting threshold is the critical number. Most pension funds require five years of qualifying service to be vested. If you spent two years working out of a local in another state and earned contributions to their fund, then never returned to that jurisdiction, you may have hours in a fund you will never see a dollar from — because you never crossed the vesting threshold. Multiply that by two or three jurisdictions over a career and you can lose meaningful pension benefit.
The fix is not complicated but it requires asking the question before you take the dispatch. Call your home local's pension administrator. Ask them whether the jurisdiction you're going to work in has a reciprocity agreement with your home fund. If they do, your hours transfer cleanly. If they do not, get a clear explanation of what happens to those contributions and what the vesting requirements are in the host fund. Then make the decision with the full information. I made it without the information. I would not make that mistake again, and I don't want you to either.
