I can assure you it is the reality - i am middle management and at my level i am expected to work on public holidays if there is a crisis, CEO's with their ungodly salaries are expected to do much more ( though they tend to drag down their teams with them aka "If i have to work so do you!"). And you would be mistaken how far top law firms are willing to go for their client, they will work on holidays but you can expect premium rates for these services. They do this though ( and getting paid very well) just to keep these huge studio and media corporation clients - this is a mindset both on the CEO and top lawyer firms that few people can understand but you will not get that high up the chain if you're not willing to go that extra mile.
The fact that they won't conclude negotiations this year and are not negotiating until early next year points to my point of this being a deliberate tactic to put financial pressure on the union members ( Thanksgiving/Christmas/New Years around the corner and no income) in the hope to resume early 2024 with a point being made by the studios, i.e. we have deeper pockets.
And i don't understand what your point about subscribers not plummeting means - did you intend to correlate possible actor residuals being tied to subscribers? if so that's wrong - the only metric that counts for all is viewer count, i.e. how many viewers streamed any given show or movie. Ad companies use this metric to negotiate prices with the streamers, streaming services use it to calculate interest in their service that relates to how much they can charge for it and actors are paid residuals based on how many of their shows/movies are being watched ( and paid less than pennies at the moment for it which is one of the main issues).
