Pharm Tech Pay is So Low ???

Been working at front of store for almost half a year now and decided to cross train into pharmacy (thinking it was gonna be a good way to earn a little extra cash) but holy shit its so not worth it lol. I've been training for the last 3 weeks, and everything I've seen makes the pharmacy seem like the 10th circle of helllllll. Before getting the position, the store manager told me that I'd be making $15/hr in the front, and $16/hr in the pharmacy. I finally get the job, and I find out that I'm only gonna get paid $15.50 in the pharmacy while doing 100x more work than the front store. What the hell is going on with CVS ????
