Why You Need This Service

  • Is your aggrieved employee list out of date or is the contact data limited or incorrect?
  • Do you need to talk to more witnesses and declarants to move your PAGA case forward?
  • Are you struggling to locate employees in transient and short-term jobs?

    The Tristar Solution

    • We identify hard-to-find employees that have low data profiles.
    • We excel in industries such as fast food, labor, agricultural, and retail.
    • Our lists include names, addresses, phone numbers, and email addresses.

      Problems We Solve

      Do you need to identify and locate aggrieved employees? Is the defense counsel dragging its feet on turning over a class list or is it outdated or incomplete?

      Are you faced with looming discovery deadlines, opposing an MSJ, or the need to wrangle witnesses for trial or declarants for a class certification motion?

      Finding quality witnesses within optimal time frames can be frustrating and slow. Employees sometimes drop off the radar or maybe that witness who seemed perfect suddenly won’t respond to emails and phone calls.

      Details: How It Works

      1. Proprietary Methods

      Tristar Investigation conducts thorough employee research projects for numerous law firms across California. Our team has developed sophisticated protocols to not only find employees, but our proprietary approach to finding accurate contact information is unmatched.

      2. Fully Compliant

      All of our research is conducted in compliance with state, local, and federal privacy statutes and other relevant regulations.

      3. High Quality Lists

      When the research is complete, it is packaged into easy-to-use spreadsheets for your outreach team. Our lists include full names, current addresses, and multiple phone numbers and email addresses where available.
