The Seafarers International Union of North America (SIUNA) is a collection of autonomous labor unions representing various categories of sailors and other employees aboard ships flagged in the United States and Canada. It is a member union of the AFL-CIO.
In 2026, the Seafarers International Union disclosed alleged financial misconduct involving Chelsea Diab, the daughter of union president David Heindel and former treasurer of two union-affiliated political action committees. Federal Election Commission filings accused Diab of a multi-year scheme to misappropriate PAC funds and file false reports with the agency. The union stated that an internal review led to her dismissal and reported efforts to recover the funds, including insurance reimbursements and restitution payments. As of May 2026, no criminal charges or confirmed law enforcement investigation had been publicly announced. 1
