284.2. The Commission may make, with a group of employers it considers appropriate, an agreement determining, in particular, the special conditions governing the application to the employers of personalized rates or retrospective adjustment of the assessment as well as procedures for calculating such rates or adjustment. The Commission shall determine, by regulation, the framework within which the agreement is to be made.
Such an agreement may depart from the prescribed conditions and procedures used to fix an employer’s assessment and shall provide that disputes resulting from its application are to be submitted to arbitration and are excluded from any other remedy under this Act.
