The Company doesn't want rotating days off so even if other stations, usually junior stations, were interested they wouldn't be able to overcome that hurdle. During the '08 CBA negotiations, a few stations stood in solidarity with NYC in order for them to keep their written agreement for rotating days off.
Today ,that might be in jeopardy because NYC doesn't have anyone at the table and the importance of that agreement to NYC might be underappreciated.
I worked with rotating days off and I didn't mind it at all. Usually those that can make steady weekends off are against it, while everyone else enjoys the ability to get weekends off every once in a while. Not to mention being able to get holidays off but not be stuck with a Monday/Tuesday all bid to do it.
