Pausing - yes, if we worked fewer hours and those hours we worked were predictable, of course we would be happy to be paid less - in fact some of us do - as a very junior doctor I did 4 months general practice, I could only work when there were enough people to supervise me so I worked 9-5ish with no on calls. For that 4 months I was on basic pay.
When I worked in anaesthetics, 2 of my colleagues had chosen to come out of training - they worked 8-5, they did predictable lists, they didn't do on calls, they got basic pay. It suited them, they preferred the lifestyle, and it suited the trust, in that job there were already enough people to do all the emergency stuff, these doctors doing the shifts they did meant the trust could offer more elective procedures.
However, the job I do now (intensive care transport) is entirely emergency work. I work loads of nights and weekends. I'm often busy all night. I often finish late. I may not get a break at all. Sometimes if we have a gap in the rota, one of us has to work extra to fill that gap and get paid extra for it or have time off in lieu when there are more people around. I'd love it if there were no gaps in the rota, I'd rather work my allocated hours and then have my allocated days off than work my allocated days and a bit more and get a bit more money.
I wouldn't be happy to be paid considerably less for my normal working hours though, as I think that what I'm paid reflects the intensity of my shifts - my workload at night and on weekends is greater than some other specialities and, as we have the same number of doctors regardless of the time of day or day of the week, I do proportionally more out of hours work than some other specialities.
