Then you need to learn about
RECIPROCITY
The I.B.E.W. National Reciprocity Agreement states that each Local’s Benefit office is to reciprocate all hours / contributions within thirty (30) days of receipt to the “home” Local that the participant designates within ERTS (Electronic Reciprocal Transfer System).
If you are scheduled to work within another I.B.E.W. Local’s jurisdiction, this is what you need to do after “clearing” in with that Local’s Union Office.
