I work at a non profit and we just won union recognition and are slowly moving towards first contract negotiations and I HAVE NO IDEA WHAT I'M DOING. Would love to chat with some folks about their experiences, especially if you've negotiated around contracts/grants/etc.
Just talk to anyone who's in a big union, especially if they are in a small shop. If you can even find one. A lot of unions wouldn't have even consider a place like you describe because not enough due$.
