Working as a technician vs a pharmacist is like comparing orange vs apple. It's two different world in the same setting of work enviroment. I have never worked as a technician...however, i used to work as an intern during pharmacy school year, so pretty much , i performed intern's job + some pharmacist's job.
Here's what i think. Jobwise, technician has to deal with more craps than a pharmacist, especially if you work for retail setting...dealing with customer isn't easy. But it all boils down to the pharmacist' responsibilities. If a customer complains, the pharmacist will be the first one to response for such complaint. Or if a wrong med is given, it's the pharmacist's responsibility....
Now, that doesn't mean pharmacist will get an easy job either. We have to deal with doctors, nurses all the time...lots of different headache, we're also responsible for so many things at the same time: in retail: phone rings, patients are waiting for meds to be picked up, MD on the line for a follow-up. Patient is waiting at the cashier to be counseled....you name it. In hospital, imagine yourself being the only pharmacist in the pharmacy, phone rings, technician needs floor-stock/cassesste checked to be delivered, IV tech asked for IV checked, then you have a new Stat ordered faxed down for a Versed Drip and you're the only one who can open the control cabinet....things like that happens very often.
Knowledge wise...hm...well, i respect my technicians in a way they're so helpful to help out with their job and without technicians, my work would be chaotic. Technicians are trained to do technician's job, mainly filling and dispensing medication, answering phones (hopefully). But there is no way i would feel comfortable to have a technician talking to an MD about drugs. Why? Because they don't have enough training in depth in medications. If that's the case, they should have gone to Pharmacy school and get a Pharm.D. Say if the MD is on the line and asks for a change in Lipitor for another similar medication because Lipitor is NOT on formulary, a technician may/may not be able to answer it...but what if he asks, "is it okay to take Lipitor with Amiodarone and Cyclosporine? and my patient is acute renal failure, liver enzyme is elevated today 3x then yesterday...", or a nurse ask, "Is it okay if i push Lasix 80mg for 1-2 mins?". I don't think the technician would be able to answer in such cases...Now that's the difference!
There are lot of things pharmacists can do, and technicians can't (due to law + even if law allows, tech can't do it...).
As of motivation, it can vary from person to person. Some will quit in between because they think pharmacy is a boring career...since they don't work as the pharmacists, they see the outside...some feels it's a great career...so it depends.
