I'm shocked to hear that Pharmacists get paid that "low" in the UK. I know a handful of Pharmacists here in the US both in retail and hospital, and the retail ones work about 40 hours for ~$120k (~£78k), and the hospital ones work about the same (yet seem to enjoy their job more) for ~$90-100k (£59-65k)
Of course this is in the New York City metro area and the surrounding suburbs so take that with a grain of salt.
My girlfriend is in retail pharmacy and doesn't really like it, she says she's 'taking years off her life'. Thankfully she's naturally frugal and since currently is still living at home making $120k she's saving very aggressively to be able to downshift into per diem work.
It might sound cynical, but dealing with the 'general public' can be bothersome. My girlfriend often spends 8-12 hours on her feet getting yelled at, coughed on, swamped with work, getting propositioned by people with fake prescriptions for controlled substances, etc.
Just my two cents from external observation, I work as an engineer so my workplace dynamic and career path is totally different from hers.
