Should a one person IT Department be in on Management Team Meetings?

Our organization has recently restructured and as a result the IT person is now supervised directly by the director of the agency. The Management team consists of each Departments supervisor, the Director and another person who acts as the personnel officer and adminstrative assistant. My Question is do you think that the IT person should be at those meetings? Or just hope to get representation through the director? What is the best way to approach this? Any tips or advice would be appreciated.
