Our language already has a definition for work:
Activity involving mental or physical effort done in order to achieve a purpose or result.
Isn't that acceptable?
Also I think we should note the "service" part of Service-to-others and Service-to-self. Service-to-others isn't really about accepting everything, it's about serving everything, and likewise Service-to-self is about being self serving.
so maybe
STO - Orientation of mental or physical effort towards serving all creation.
STS - Orientation of mental or physical effort toward serving self.
Gets iffy though, since I'm sure at least some STS entities believe they are serving all creation as well.
