Sure, there’s plenty of “staff”, but not enough pharmacists. They pay them astronomical wages, then expect them to do the work of 2 pharmacists. Recipe for medication errors, some of which could injure or even kill someone.
I’ve never seen an idle pharmacist. Likewise, I’ve never seen a short order chef.
Maybe some form of automation is the answer where the pharmacist is less saddled with the grind of measuring and filling. But would something like that ironically trigger a strike?
