NRAAS Question: Junior Position Bosses.

No, but even in the military they are to be considered as such if they are the ones burdened with the tasks of keeping personnel records and "calling in" the payroll. :)

The setting you want is NRaas > SP > General Options > Options:Careers > Manage Bosses > True (is True by default)
(NRaas SP Career module required)

If you do not have this one on True or if the SP Career module is not present, then the EA random boss assignment method is in place.

Either way though, if you don't like the assignments you can change them with MasterController.
NRaas > MC > (Sim) > Intermediate > Career > Choose Boss
(MC Cheats module required, it's always something isn't it?)

Got all of them. :) It's so convenient to have them...and I just kept adding them until I got the "whole set"... :D

Youve never had a boss do less work than you??? :D

My sims usually end up higher than their bosses because they get promoted faster than I allow the inactives to be.

It's possible then that these bosses were assigned when the target sim was at a lower level, has since surpassed them, and SP hasn't "caught up" and reassigned yet. But I never found that procedure to be infallible, that's when I shrug and reach for the MC fix as needed. And that would be provided there actually are any sims at a higher level in that career than the target, sometimes of course they are the ones on top but they still require a "boss."
