If there are no significant changes in the position you are recruiting for, submit the requisition on line via Blu. If the position is new or is an existing position with significant changes in duties since it was last filled, you also need to submit the Job Description form and the Physical, Environmental, and Mental Demands (PEM) Form for classification review by the compensation analysts (see Chapter 3, Classification, The Classification Process). After review, Compensation will notify you of the results. You will then need to submit your requisition on line via Blu.
