The law firm Edelson Lechtzin LLP announced it is investigating data privacy claims related to a security incident at the Teamsters Union 25 Health Services & Insurance Plan (HSIP). The firm is exploring the possibility of filing a class-action lawsuit on behalf of those affected.
HSIP discovered unauthorized access to its network around August 1, 2025. A subsequent investigation revealed that an unknown individual gained access and potentially copied data.
The compromised data may have included personally identifiable information such as names and other identifying details. HSIP immediately secured its systems after detecting the breach.
Edelson Lechtzin LLP is urging individuals who received data breach notifications from HSIP to take steps to protect themselves. This includes carefully reviewing financial statements and credit reports for any unusual activity.
The firm specializes in class-action litigation, including cases involving data breaches, securities fraud, antitrust violations, and employee benefit plan disputes. Edelson Lechtzin LLP has offices in Pennsylvania and California.
Marc H. Edelson, an attorney at Edelson Lechtzin LLP, is leading the investigation. The firm is encouraging anyone affected by the data breach to contact them to discuss their legal options.
The Teamsters Union 25 Health Services & Insurance Plan is a non-profit organization providing health and wellness coverage to eligible union members, retirees, and their dependents. The extent of the data breach and the number of individuals affected remain unclear.
Edelson Lechtzin LLP’s investigation will determine whether a class-action lawsuit is warranted and will explore the legal remedies available to those whose data was compromised. The firm’s focus is on securing compensation and other forms of redress for those affected by the breach. The firm stressed the importance of proactive steps to mitigate potential risks associated with identity theft and fraud.
