Unfair Labor Practice (ULP)

What is Unfair Labor Practice (ULP)?


‘Unfair Labor Practice’ or ‘ULP’ refers to the unfair labour practices defined by the National Labor Relations Act (NLRA). It is a part of the US labor law and in cases where the companies are found to violate it, the National Labor Relations Board (NLRB) investigates the case.


Concerning ULP, one needs to understand that every unfair act in the workspace doesn’t amount to an ULP and it is defined by the NLRA. The definitions are also constantly updated and the latest list can be found on the NLRB website.


There are 5 different categories of ULP defined by the NLRA:


  • Interference, restraint, or coercion.
  • Employer domination or support of a labor organization.
  • Discrimination on the basis of labor activity.
  • Discrimination in retaliation for going to the NLRB.
  • Refusal to bargain.
