Some junior doctors have been asked to leave the picket line and return to work because of what the British Medical Association have called "poor planning".
Dr Mike Greenhalgh, from the union, says they're meeting NHS bosses four times a day to make sure other contingency plans in place.
Dr William Oldfield is Medical Director at Kingston Hospital.
He says the junior doctors’ strike should not stop people who are having a genuine medical emergency from attending the site.
