The event, which was held by Barnsley People Before Profit and Barnsley Trades Union Council (BTUC), was socially-distanced and those involved were wearing masks.
George Arthur, BTUC secretary, said: “Health Secretary Matt Hancock claims that over the past three years nurses have had a 12 per cent pay rise.
“Unfortunately this is typical of government statistics.
“The reality is that since the year ending August 2010, when the NHS started publishing these statistics, average nurse pay has fallen by 7.4 per cent in real terms.
“That means the average NHS worker earns on average £3,800 less than they would have if salary rises had kept up with inflation since 2010.
“Fellow trade unionists cannot stand aside and let nurses who have worked so hard during the pandemic be treated so badly by the government.
“If nurses are forced to take industrial action to win the pay rise they deserve then BTUC and campaigners will give them full support.”
