The strike will be on Tuesday, May 23, and is aimed at demanding “revision of pay and allowances and other issues,” the bank said.
The Forum represents a section of its employees and officers, it added.
The strike call is a result of what the employees see as a failure by the bank to keep its promise for wage revisions by May 8.
A similar call was taken back in April after the bank agreed in front of Deputy Chief Labour Commissioner, New Delhi for wage revisions for its employees before May 8.
Employee unions such as All India Bank Employees Association had started talks with the management after the compromise arrived on April 12.
The issue of wage revisions has been on the boil for several months.
The unions allege that there has not been a revision in salaries for several years
