Dr Paul Thorpe and junior doctor colleagues in Bristol hold up a British Medical Association card protesting about long hours and low pay.
Junior doctors voted at this year's annual conference for industrial action if pay negotiations with the Department of Health fail.
A ballot on action, from providing an emergency-only service to total withdrawal of labour, could be launched as early as next month. But talks with DoH officials are continuing over the summer.
The BMA junior doctors committee wants an end to the system where on-call hours are paid at less than the normal rate.
