But everyone can benefit. Almost everyone can adopt a child. If they choose not to, and then they are choosing not to avail themselves of that employee benefit.
My employee offers 3 days funeral leave for the death of a parent/sibling/spouse/child, is it "fair" if I don't get to use those days, either because everyone in my family is already dead, or maybe I was raised in an orphanage and don't have any relatives?
My employee offers a discounted rate if one gets their cell phone through a certain provider, is it "fair" if I want to use a different cell provider, so I don't get the discounted rate?
Is it "fair" that my comprehensive health insurance includes vision benefits, but I don't wear glasses, so I'm paying higher premiums without any benefit, in effect, subsidizing my co-workers who wear glasses?
Or cancer insurance. Is it "fair" that my co-worker gets cancer and gets all the benefits of her/his cancer insurance, but I'm paying the same premiums and don't get any benefit because I'm healthy?
Do you see how ridiculous this sounds?
"Fair" means everyone is being treated equally, whether or not an employee chooses or is able to cash in on any particular benefit does not mean they are not being treated "fair"
