Whole sector shrinking, should I change fields? after 13 years as a store manager

Our sector has been shrinking and I am unsure if I should wait it out. I would rather hear the honest version than the polite one. I am open to a pay cut if the field is stable. Who has switched fields?

Thanks for writing this out. I went through something close to it 7 months ago, and it settled down once I kept a simple log of every call and form.
