It can be stressful. So much depends on where you work, and who you work with.
I'm incredibly lucky to have a lot of seniority and work for a great hospital. CVS, Walgreens,
Walmart...well, it can be incredibly stressful partially due to staffing (understaffing) and partly due to underinvestment in things that make the pharmacist's life easier, like better software, automatic counting trays, etc. It doesn't help that salaries have not kept pace with inflation, either (this is due to reimbursement not keeping pace, most likely). And yes; controls have a lot of hoops and always will take longer! If you sign up for automated texting your life will be easier at the pharmacy and you a just show up when the medication is ready. It takes a long time to fill medications because there are SO many in process; when you show up you are probably one of many hundred in process, and those ones have to be worked on, too, so when those people (hopefully) show up, they are ready or close to ready.
In 2026 it isn't a career I recommend for anyone unless they already have a lot of proven experience in the field as a pharmacy technician already, but it can be rewarding at times. I don't regret it, but I'd consider alternatives first and think hard before pursuing it as your time is your most valuable asset, pharmacy school is four long years (usually) after college, and other potentially more personally and/or monetarily rewarding alternatives exist.
