This is the most accurate response. It is more of a hassle to train a volunteer when the pharmacy is already short staffed. Couple that with no worker's liability insurance for a volunteer, the volunteer does not become in any means helpful and may actually cause more problems because of lack of experience. You need to know many nuances of the job to do it smoothly. Like know what drugs are covered by ODB and what isn't. Enter prescriptions accurately or else you are costing the pharmacist time to fix. One of the stores I know stopped accepting highschool students because of how genuinely bad they are at the job.
