While there is often a small chance you could get laid off (for instance, if the chain supermarket closes some stores) you should not have much problem finding another job. When all factors are viewed, however, I would need to say how the prices charged at CVS Pharmacy and Rite Aid Pharmacy may be comparable. Most drugs need being stored at exact temperatures, so one in the things pharmacists learn as part of pharmaceutical quality training is the necessary steps to keep the facilities clean and in compliance with regulations.
