At Mangan Law, we offer a comprehensive range of legal services for federal civilian employees. Whether you are the victim of workplace discrimination seeking justice through the EEOC, or a dedicated professional defending your career against allegations of misconduct, we provide an elite level of advocacy that covers the entire spectrum of federal employment law.

Defending Against Administrative Investigations and Adverse Action

Workplace allegations can be just as damaging as an EEO claim is restorative. For civilian Department of Defense (DOD) employees, the stakes are uniquely high. Sean Mangan brings an unparalleled background to this specific fight:

  • Law Enforcement & Investigative Expertise: Sean leverages his deep experience as a former law enforcement investigator to dissect the government’s evidence and identify flaws in administrative probes.
  • Former Chief of Administrative Law: Having served as an Administrative Law Attorney and then the Chief of Administrative Law for an Installation Legal Office, Sean has a “behind-the-scenes” understanding of how Army legal advisors handle workplace misconduct allegations against civilians.  
  • A Proven Track Record: Over the last six years, Mangan Law has successfully helped several DOD civilian employees defend their careers against proposed adverse actions, guarding their due process rights and preserving their professional reputations.  The secret to our success?  Take a proactive approach!  Do not wait for an allegation to become an adverse employment action.  Get help while the investigation against you is still underway.

While Sean spearheads the defense against administrative allegations, our federal employment law specialist, Paul “PJ” Judge, leads the charge in proactive employment litigation…

Expert Representation in Employment Litigation

When your career is in jeopardy, you face an opponent with the unlimited resources of the federal government. To level the playing field, you need an attorney who has seen the system from the inside. Paul “PJ” Judge, a partner and our federal employment law specialist, brings a unique “Government-to-Defense” perspective to every case:

  • Government Experience: He previously served as an employment law attorney with the Department of Commerce, advising the Census Bureau and the National Oceanic and Atmospheric Administration (NOAA) on internal employment matters.
  • Proven Results: In the last year alone, PJ has secured multiple cash settlements for federal employees in high-stakes EEO matters.
  • Trial Tested: Before his civil service, he “cut his teeth” as an Army JAG, trying felony-level cases in military courts-martial.

Frequently Asked Questions

  • Can you help me if I am currently being investigated by my agency? Yes. Early intervention is critical. We guide you through the investigation process, advise you on your right to remain silent, and help you prepare for interviews to prevent an administrative error from becoming a career-ending action.
  • What should I do if I receive a “Proposed Removal” notice? Contact us immediately. You have a very limited window to submit a written and/or oral response to the deciding official. This is the phase where Sean Mangan’s experience as a former Chief of Administrative Law is most valuable.
  • Does Mangan Law handle “Reasonable Accommodation” denials? Yes. We assist employees in securing the accommodations they need under the Rehabilitation Act, including telework, ergonomic equipment, and flexible schedules.
