Hundreds of thousands of health workers walked out on strike today, many for the first time in their lives, in protest at the Government's decision not to give them a recommended 1% pay rise.
Midwives, nurses, paramedics, ambulance staff, and hospital porters and cleaners mounted picket lines across England from 7am for four hours, while action will be taken later today in Northern Ireland.
The NHS strikes in Northern Ireland have seen more than 4,000 health workers take to the streets in protest against "a stark fifth year of pay freeze."
Nurses, healthcare assistants, ambulance staff, porters, administration workers and cleaners have been taking part in the four hour strike which started at 11am.
Patricia McKeown regional secretary of Unison, which has 25,000 members in Northern Ireland, said: "Our people are facing a stark fifth year of pay freeze and that is having a very adverse impact, particularly on the lowest paid of health workers.
"We have seen an enormous rise in the number of our members having to turn to the benefit system in order to make ends meet."
With thousands of NHS staff expected to go on strike today in a row over pay, here is a list of those hospitals affected.
A fifth of health workers have at least one extra job because they cannot survive on an NHS salary, survey reveals.
