I suspect management covers all the professional grades as well you know the HR, marketing, securitty and professional engineers not just those with strict line management roles.
Hm... I guess I got a little carried away. I still don't understand why a security instructor or an engineer would be considered management. I'm sure there's a rationale. Somebody want to help me understand this concept?
Are you considered an "exempt" grade if so HR will have to put you in the M&P (managerial and professional) group to avoid all sorts of nasty tax problems with the IRS.
