Are you able to prove that your relationship is a partnership, in other words that you have been living together for a few years in another country? If so, you should be able to have your partnership recognised by the authorities and get yourself a permit on that basis. However, that will be a resident permit, not a work permit. You could apply to have it upgraded to a work permit if you find an employer willing to apply for that.

You write as though you somehow expect that you have a right to work, or to participate in certain other parts of Swiss society on your current status, which is a temporary visitor.

Perhaps you should ask yourself what kind of "rights" are afforded to people in the same situation in your own country (i.e. the US).

While I strongly disagree with some of the politics here concerning work permits, I must admit that it does kind of bug me when people somehow feel as though they have some sort of automatic right to be here and work, especially if those people come from a country where the situation is even stricter.
