The bank employees will now also get holidays on two Saturdays in a month.
"Long pending demand of holiday on second and fourth Saturdays for the bank employees have also been reached," AIBEA General Secretary C H Venkatachalam said.
Last week, Finance Minister Arun Jaitley had appealed to bank employee unions to call off their strike as talks were on for a revision of wages of employees.
The minister said banks are already in negotiations with their unions and associations for wage settlement and "the bipartite negotiations in a cordial manner is the only available tool for settlement".
The wage revision of public sector bank employees has been due since November 2012.
Earlier, unions had deferred one-day strike scheduled for January 7 as IBA improved the wage hike offer to 12.5 per cent from 11 per cent earlier.
