There were vacancies for as many as 20,785 officers and 12,695 clerical level posts as on March 31, 2012, Minister of State for Finance Namo Narain Meena said in a written reply in the Rajya Sabha.
Also, there was vacancy for 7,666 subordinate staff, he added.
Meena said banks undertake recruitment of staff to fill vacancies on ongoing basis as per their requirement.
"At present, there is no proposal to revive Banking Services Recruitments Board as recruitment is done by individual banks on an ongoing basis...," he added.
Requirement of manpower in nationalised banks depends upon the business volume and growth, employee strength and retirements, besides other factors, the minister said.
As per the details given by the minister, maximum number of officer level posts were vacant in UCO Bank (3,747) followed by Central Bank of India (2,854), Bank of India (2,802) and Punjab & Sind Bank (2,500).
