TWU Local 100 Data Breach Impacts Member Personal Information

Transport Workers Union Local 100, a key labor organization for transit employees, has disclosed a data security incident to the Massachusetts Attorney General on April 24, 2026. This report confirms that sensitive personal information entrusted to the union may have been compromised through unauthorized access. The union's role in managing member records means it holds substantial amounts of sensitive data.

While the full details are still under investigation, incidents involving organizations like trade unions often expose sensitive personal information. This type of data can be highly valuable to cybercriminals, who may seek to exploit it for financial gain or identity-related crimes. The exposure of your information can lead to significant long-term risks, potentially affecting your financial security and personal privacy.

As an organization that collects and stores member data, Transport Workers Union Local 100 has a legal obligation to protect that information with robust security measures. The occurrence of a data breach suggests that these safeguards may have been inadequate. Under Massachusetts law, individuals whose data is compromised due to insufficient security may have legal rights to seek recourse.

If you received a notification letter from Transport Workers Union Local 100, it's crucial to take proactive steps to protect yourself. Carefully review the letter for any specific guidance offered. Monitor your accounts and personal statements for suspicious activity and consider placing a fraud alert on your credit files. Be wary of unsolicited communications that claim to be from the union or other entities, as these could be phishing attempts.
