If you marry your fiancee, or register her as your domestic partner where such registries are available, or log her into such benefits programs as you are eligible for and which cover your “family” (however defined) including a DP, then she would be eligible. Domestic partner registries are not gay-exclusive; they provide a means for “term marriage” for heterosexual couples who want to commit but not necessarily the lifelong hard-to-break commitment of traditional marriage. She is, and should not, be eligible for your benefits until you formalize the bond in some way (even if it’s just listing her as DP with your benefits provider). The whole idea of such benefits is to provide them to persons with whom the employee has a significant bond (parentship, including adoption and guardian-ward status, marriage, including DP-ship, filiation (i.e., your parents or those who raised you in the absence of parents)…“Family” in a broad sense. As your fiancee, she has acknowledged intent to formalize a bond with you, but has not done it.
And no, I don’t see any special rights. My wife is dependent on me (or on finding a job in an industry where eight years of greater computerization have passed her by since she left work), and benefits I can provide for her are my right, duty, and privilege. And if I had a gay coworker who made a similar commitment to his/her S.O., he/she would have the exact same responsibility towards that S.O.
Oh, and dlv? “PC Media”? That would be message boards (communications Media) accessed by PC’s?
