M. Collin Quigley represents and advises employers of all sizes, from small startups to Fortune 500 companies, in a broad range of employment matters brought before federal and state courts and administrative agencies. His practice primarily focuses on complex litigation involving trade secrets, noncompetition and nonsolicitation agreements, wage and hour violations, discrimination, retaliation, harassment, failure to accommodate, and wrongful termination.

Collin prides himself in his ability to think outside of the box in his litigation strategy, utilizing technology and electronic and third-party discovery whenever possible to successfully defend his clients from claims brought against them.

Collin is often called on to act as a core team member on complex litigation matters, including nationwide collective actions and mass arbitrations involving wage and hour claims. In this capacity, Collin has had the opportunity to both first- and second-chair several arbitrations through final arbitration hearing, playing an integral role in successfully obtaining final awards in favor of his clients.

Some of Collin’s notable successes include:

  • Obtaining contempt finding against former employee in a high-stakes unfair competition matter for violation of the court’s permanent injunction
  • Successfully defending against workers’ compensation retaliation claim with the use of cellular geo-locational data demonstrating plaintiff was not “on the job” at time of underlying injury
  • Obtaining favorable settlement, including a permanent injunction, by utilizing cellphone data to demonstrate opposing parties intentionally destroyed material evidence
  • Obtaining voluntary dismissal of a sexual harassment claim by demonstrating primary evidence relied upon by the plaintiff was fabricated and manufactured using an online tool

Prior to joining Littler, Collin began his career practicing with a Dallas-based litigation firm, where he gained extensive experience defending his clients from civil and commercial claims. During law school, Collin was an assistant managing editor for the International Law Review Association and chief counsel for the SMU Civil Clinic. In his second year of law school, Collin externed for the Hon. Mark X. Mullin in the U.S. Bankruptcy Court for the Northern District of Texas.

Prior to attending law school, Collin spent a year as an international volunteer for the nonprofit organization Nuestros Pequeños Hermanos in Miacátlan, Mexico, where he cared for and taught English to orphaned and abandoned children.
