Will we be seeing a new fleet style contract in other departments?
No need. Other departments have things called "negotiators" whose vocabulary stretches beyond "NO".
Also, most other groups have already made plenty of concessions over the years, without using the BASSA technique of "I'm alright Jack". Possibly if BASSA hadn't carved off most of their membership onto inferior contracts and sold them down the river (LGW?), the old contract CSD's wouldn't have become so isolated.
