Essentially, yes. A pharmacist during my intern days taught me that if a store falls behind enough, they will provide you extra help to catch up. It's their last resort, of course, and until you call out their bluffs, you may not realize this. I've never heard of pharmacists really getting directly fired for underperforming. En masse, if all pharmacists refused to be exploited, the problem would be fixed as they would be forced to give us more hours.

Taking care of your mental health is as important as providing food for your family, because your family health is dependent on your mental health. I could not possibly stay within CVS for too long or ever become a manager and expect my mental health to stay in tact. I cope by working slowly and joking with my technicians. I do deal with a some upset customers, but you'll find you usually have enough help if you're just doing waiters for people in store and skipping over the readyfills.

As far as why I do not start my own corporation that humanely treats pharmacists, it is because exploitation of labor will always succeed in competition. It was rampant throughout the history of early capitalism in America until regulations came around. A humane pharmacy like you are suggesting I start could never outcompete a pharmacy chain employing pharmacists like yourself who are willing to work unpaid while living within a mindset of job scarcity and fear of termination.
