According to the BSD report, banks last year cut back on the number of managers in favour of more supervisory roles.
According to the data, In 2009, the banking sector increased the number of managers on its payroll by 6.4 per cent to 23.5 per cent.
During the same year, the banking sector reduced the number of supervisors, clerical and support staff.
By last year, the banking sector employed 1,620 employees of whom 917 were supervisors, 679 were clerks, and 24 support staff.
The changes in employment patterns captured what had been happening on the ground.
Barclays Bank last year set the tone for layoffs of senior bank managers in January 2010 when it sent home 200 managers.
Co-operative Bank followed suit, sending home four chief managers, four senior managers, and another 26 middle level managers.
Equity Bank also cut the size of its executive suite from 14 to nine managers. This follows the merger of directorship positions of marketing and treasury, human resource and customer service.
Heads of banks say the changes were brought about by the need for a leaner structure.
While bank managers faced the purge last year, directorship positions continued to earn higher, in what the industry attributed to a vicious talent wars in the quest to boost profitability, and increase market share.
