Banks will remain open on Sunday, September 27, ahead of a three-day strike planned from September 28 to 30 by bank employee unions.
The move is aimed at reducing disruption to customers and allowing important transactions to be completed before the strike. Government salaries are expected to be credited by September 25.
The unions are seeking a five-day banking week, pension reforms, higher recruitment and staffing, and changes to performance-linked incentives.
Public sector banks and regional rural banks are expected to see the biggest impact if the strike goes ahead.
