The FDA has 14,000 employees; its FOIA office has 10, and they go at roughly 80,000 pages per month, meaning each employee does 8,000 pages per month, or roughly 400 per working day per employee, less than a minute per page. That to my non expert opinion sounds pretty fast.
That speed has been appropriate until now that the plaintiffs want 4 months' worth of FDA FOIA work for yesterday.
I agree that there should be a solution for these cases, but it's this particular FOIA request that's the anomaly, not the FDA way of work.
