Please show me an instance where a biotech company has voluntarily laid off manufacturing staff to resolve a short-term issue that had nothing to do with the demand for the company’s products. I don’t think it’s ever happened.
Genzyme comes immediately to mind as a company that did layoffs largely because of a known-to-be-mostly-transient problem. And they were in a MUCH better financial position than Dendreon (they were cash flow positive even with their issues and had a huge cash war chest).
I am sure I could find others as well - but it is hard to find biotech companies where it is unambiguous that the company knows in advance that the problem is largely transient.
PS Although the above post is responsive to you challenge I actually disagree with your trying to limit this to biotech. Biotech isn't special wrt doing layoffs when faced with transient issues - e.g. most other kinds of companies also require special training for RIF'd employees.
