The main justifiable complaint by junior doctors is that of being over-worked. Unfortunately the OP and the link above suggest that this is a problem partly self-inflicted by the profession itself.

There isn't a great risk of emigration by UK-trained doctors, as evidenced by an over-subscription for training places. Further, OECD data show that when adjusted to average national salaries, the pay scales for clinicians in the UK are competitive with the main destinations, including Australia, Canada and NZ [0].

A large part of the solution would appear to be increasing undergraduate medical education and further professional training slots. This would need increased government funding as well as agreement from professional bodies.
