In Britain, every nurse is on a grade (ранг). The grade depends on experience and skills, and each grade has different responsibilities and pay. On the bottom grades are unqualified auxiliary nurses who do the routine work on hospital wards. On the top grades are nursing officers, who are usually administrators.
Auxiliary nurses are on the bottom grades, but student nurses get the lowest pay. However, students don't stay at the bottom of the pay scale forever. When they qualify, they start working on a middle grade. As they get experience, they can get promotion and move up the ranks to become staff nurse, then sister (charge nurse if a man), and perhaps eventually nursing officer.
Many nurses work shifts, and often they work overtime (сверхурочно) to earn more money. After basic training, many nurses choose to do further study and become specialists. Nurses can specialize in many different fields there are triage nurses working in Casualty, and psychiatric nurses who treat the mentally ill. There are health visitors who visit patients in their own homes, practice nurses working in GPs' surgeries, and mid wives who deliver babies.
Many of them say they do not get enough pay and respect for the work they do. They say that the work is physically and mentally hard, that they work long hours and get very tired. But they also say that there are many great rewards which have nothing to do with money.
