Representative Matters

  • Successfully represented a major telecommunications company in an arbitration involving claims of repetitive trauma injuries.
  • Represented an American fast-food chain in a claim by a former worker alleging carpal tunnel syndrome from job duties. The Arbitrator found that the Petitioner failed to prove an accident arising out of their employment and denied all benefits.
  • Represented a national restaurant chain against claims in which an employee was seeking temporary total disability (TTD) benefits and knee surgery authorization for an alleged accident that took place at work. Jill proved that the injuries were the result of a significant preexisting condition. The Arbitrator denied all benefits to the Petitioner.
  • Represented an American fast-food chain against claims that a contractor required surgery because of a slip and fall that took place when he was walking into the establishment. The petitioner was seeking TTD benefits, payment of over 100 visits to the chiropractor and payment of their surgical bills. Jill successfully showed that there were questionable elements in the complaints and medical evidence. The Arbitrator denied the petitioner all medical after the first few weeks following the incident.
