Please show us an instance where a biotech company has voluntarily laid off manufacturing staff to resolve a short-term issue that had nothing to do with end-user demand for the company’s products. I don’t think it’s ever happened.
Skilled biotech-manufacturing personnel are not a dime a dozen. It would be colossally wasteful to fire such people and then have to train replacements a short time later.
