Same boat. The pay was mediocre, the hours were bad and far too many, and the company used cyclical demand to keep us in perpetual fear of layoffs. Mandatory pager carry 24/7/365 unless I was on vacation out of town. Rotating weekend coverage. Rotating holiday coverage. First couple of years were 12 hour shifts on my feet, then I went to process integration and did endless meetings instead.

I loved, still love, the actual technology of semiconductor fabrication, but you’d have to pay me 8x what I was making for me to go back to the business of semiconductor fabrication.
