How do I search PERC decisions to determine if I have an Unfair Labor Practice

Go to the Decision search page. In the “full text search” box enter the type of violation you believe has occurred. If there are multiple words, use quotes around the set of words.
For example: if I believe my union has committed a “duty of fair representation” violation.

  • I’ve looked up the elements necessary to allege this type of violation in the decision tree or PDF document on the Unfair Labor Practice page.
  • In the “full text search” box I will enter: “duty of fair representation” (or I could enter “duty of fair representation” & “invidious discrimination” & “bad faith” & arbitrary)
    • Using connectors like “&, or, /w” can help narrow your search.
  • Click on “search”
  • All of the cases with my search terms will appear below the search box.
  • Read through multiple cases, paying attention to the applicable legal section – this will explain what the law is on that specific issue.
  • Also pay attention to the facts of the case to see if the it was determined that the specific facts met the criteria necessary to find a duty of fair representation violation.
  • After reading the decision do you believe the facts of your case show that there was a duty of fair representation violation? Did the union act in a discriminatory (of protected class), arbitrary, or bad faith manner toward you? If you believe your facts meet the necessary criteria, the next step is to file an unfair labor practice complaint.

    Advanced Search:
    We recommend using the “Advanced Search” feature instead of searching by collection. If you have issues or questions, please email

    Bargaining Unit Certifications:
    Find the most current bargaining unit descriptions by searching certifications under advanced search. Enter either parties' name in the full text search box and select certification in the case type box. 

    Missing Decisions: 
    Prior to 2015, closure orders following the withdrawal of a case were assigned decision numbers but not published, therefore those decision numbers will not appear. Court Citations will be referenced but not linked; those documents can be found using the Washington Courts search engine.
