Well, you hurt the studios AND the actors when you don't watch the product. The actors residuals are generally based on how much a show makes in reruns.
A Fraternity brother of mine on strike. He was on a well known TV show for 4 seasons. But that show ended 40 years ago. He was lucky enough to get a job on another series for 2 seasons, and a minor but recurring role on another series for 6 seasons. And he did the usually guest spots on the Love Boat, Hotel, and Battle of the Network Stars.
As he puts it, his challenge is stretching those residual checks into a lifetime stream of income. He has been lucky in that he can make money off the first series by going to show reunions across the nation. And he moved behind the scenes to a job Producing.
Acting can in reality be a string of part time jobs. And the trend now is that many shows don't produce 23 to 26 episodes a year, but only 6 to 8. So there is 75% less work.
