The mandatory job listing requirement under VEVRAA, which is enforced by OFCCP, states that contractors must provide information about the job vacancy in any manner and format permitted by the appropriate employment service delivery system (ESDS), which may vary from state to state. Therefore, how you list your positions on the ESDS will be based on what the requirements of the specific state where you are posting. From our experience working with all of the ESDS states, it is acceptable to post positions where the employer indicates that shifts may vary. Most states also have the option to select the number of openings you have for a position, enabling you to post once for multiple shifts.
