Nurses are starting to vote on whether they want to take industrial action
Around 270,000 members of the Royal College of Nursing are being asked for their views on how to respond to a further below-inflation rise.
The poll will ask whether RCN members want to strike or take other forms of action, although a separate formal ballot would be required by law before any industrial action.
The RCN says low levels of pay are responsible in part for tens of thousands of unfilled nursing posts.
The poll closes on May 7 and the results will be announced at the RCN's annual congress in Liverpool in the middle of the month.
The RCN said that, since 2010, the Government has inflicted a 14 per cent real-terms cut on nursing pay.
A formal pay cap of 1 per cent was introduced in 2015 after year-on-year pay freezes in the previous parliament.

The Government would be wrong to dismiss this as sabre-rattling
RCN general secretary Janet Davies said: "Patients won't get the care they deserve from a nursing workforce that is short on numbers and low on morale.
"If the Government expects to fill the soaring number of vacant jobs, it must value nursing staff more than it has in recent years. The false economy is driving people away from the profession.
"Years of real-terms pay cuts have left too many struggling to make ends meet. Nurses should not have to fund the NHS deficit from their own pay packets.
