Having run a business in R+D for the past 40+ yrs, I can definitely vouch for a slow gradual downturn. It's the flow-on effect that
does the most "damage". But it's like anything, IF you "know" people, you'll always have work. On the plus side, people do adapt,
and new types of Electronics do spring up, albeit not high volume labour. And in some areas, you can't FIND damn workers !!
I know a few companies that can't find the "right" people. Electronics does suffer more than most though, due to the specialised skills.
Are you leaving because it's "bad" where you are?
