Doctors do become very well paid later in their careers as consultants so there is probably limited amount of sympathy for the rough years as junior doctors where they are significantly underpaid.
That's true, however people can be junior doctors for a surprisingly long time so you can see why they are pissed off! I assumed it was the first 3 years after graduation or something until one of my friends who is a doctor explained it to me.
Junior doctors are qualified doctors in clinical training.
They have completed a medical degree and can have up to nine years' of working experience as a hospital doctor, depending on their specialty, or up to five years working and gaining experience to become a general practitioner (GP).
There is no government at the moment, parliament isn't sitting, there isn't a health minister, there is no one for the docs to negotiate with. All this does is further increase the backlog for operations which is not something that typically endears you to the public.
