Whole sector shrinking, should I change fields?

Our sector has been shrinking and I am unsure if I should wait it out. It has been weighing on me all week. I am open to a pay cut if the field is stable. Who has switched fields?

A short certificate helped me more than a new degree would have. Check what local colleges offer.

I moved into operations work. The skills carried over and there were more openings than in my old field.
