That would assume that CVS and Walgreens are also completely different. I have not worked for them, but I'm pretty sure there is little difference between them in both work and salary. Now talk to me about income working in a grocery chain versus working in a CVS. I'm sure many pharmacists would pick filling 200 rx/day over 500, so why do they pick the tougher job? I would say salary is a factor.
Back to your original statement, you honestly think 25,000 people would simply walk away from a job paying six figures and hit the unemployment line? You are just dead wrong. Now if there was another job they could switch to, with a comparable salary, yes. If some new chain opened up with 25,000 positions, and no timers on the ringing phone, timers on the drive through, etc, you would see pharmacists jumping on board.
Look, you seem to like your job, and that's great. I don't know what goes on in your particular store, but clearly it is far superior to what goes on in all of the above posters. Just because they don't like their job (which you are equally uninformed about their stores) doesn't mean you have to jump to the company's rescue. The thread's title asks, "Anyone actually truly enjoy working for CVS?" Your best response would have been "Yes, I do."
