Not sure which Local you belong to?
Your dispatch hall location, apprenticeship program, union book, H&W plan administrator, or pay-stub dues deduction line will identify your Local. Once you know the number, the Local's business office can produce dispatch records — foundational evidence for an asbestos claim documenting every jobsite you were sent to and when.
